About the TRS Slider: A quick overview
The TRS Slider is a wearable, adjustable device designed to improve swing path and connection. By keeping the trail arm tucked to the body, it helps prevent ‘chicken winging’ and the common ‘over-the-top’ move. Its purpose is simple – to help golfers develop a consistent, powerful, and connected golf swing.
Recently, the TRS team sent me a Slider to test and review. While I’ll be thoroughly testing it over the coming weeks and have a review out soon, I was desperate to at least try it out, so I decided to conduct a first-use data review to see if it really could improve my golf swing straight out of the box.

This is the TRS slider, and it’s without doubt one of the hottest golf training aids on the planet right now. Fortunately for me, TRS sent one of these out for me to test and review. While I’ll be doing a full review over the coming weeks, I thought this would be the perfect time to take it out to my practice area in the garden and see whether it could make a difference to my golf swing straight out of the packet. It’s safe to say it did exactly that and more.
Testing with the FlightScope Mevo Gen 2
I headed out to the practice area with a bag of Titleist Pro V1 golf balls and my FlightScope Mevo Gen 2. I wanted to track the data because there’s no point in me telling you it made a difference without having the data to back it up. I started with my eight iron, hitting some balls just to warm up properly.
Once warmed up, I tracked 13 golf balls with my natural swing. I then put the TRS slider on, made a couple of practice swings to get used to how it brings the trail arm in, and then hit another 20 to 25 shots. The first shot was a shank, but I persevered and quickly noticed massive differences. The swing felt shorter, the strike was better, and the impact position on the net was much more central.
Analyzing the data with Badger AI
After the session, I used Badger AI in the FlightScope app to analyze the results. The conclusion was clear: the eight iron shots with the TRS slider were the winner, demonstrating improvements in both distance and consistency.
Key data improvements included:
Carry distance: Gained 6.6 yards on average.
Ball speed: Increased by 4.1 mph.
Lateral deviation: Reduced from 9.4 yards right to just 2 yards right, a 7.4-yard improvement in accuracy.
Spin rate: Increased from 5,469 rpm to 6,158 rpm, providing better control.
Swing path and impact changes
The most significant technical difference was in the club path. My standard swing has an average club path of -2.9 degrees (strong out-to-in), which results in fades and slices. With the TRS slider, this dropped to -1.1 degrees—a 70% improvement that brought the path much closer to the target line.
Other technical improvements included:
Angle of attack: Shallowed slightly from -5.9 to -5.3.
Face to path: Improved from being 10.9 degrees open to just 2 degrees open relative to the path.
This combination of a more neutral path and a squarer face resulted in much more manageable shot shapes, moving away from slices toward straight shots or slight draws.
Final thoughts
I have only used the TRS slider for one session and I’m already seeing a dramatic improvement in my swing data. I intend to test this fully with every club in the bag over several weeks before producing a full review. I am genuinely excited about what this could do for my game.

TRS Slider review: The test & data gathering
I’ve seen plenty of positive reviews online, but they mostly come from touring pros or coaches who already have quality swings. As an amateur golfer, I wanted to see how it performed for someone who actually needs the help. More importantly, I wanted to see the inclusion of real golf swing data, something often missing from the reviews I’ve read so far.
I grabbed my 8-iron, a bag of Titleist Pro V1s, and my FlightScope Mevo Gen 2 launch monitor, and headed to my garden practise net.
To begin with, I warmed up by hitting 20-25 balls. Once loose, I recorded 13 shots (the number of balls I had to hand) using my normal swing. Although I’m currently rebuilding my swing for my Journey to Scratch series, I made sure to swing as naturally as possible for a clean comparison.
Next, I strapped on the TRS Slider. While I’ll cover build quality and fit in my full review, I will say it felt very unnatural at first, which is to be expected, especially with my golf swing. I took several practise swings to adjust before I began hitting balls. After shanking the very first shot, which made me even more sceptical than I had been before, thankfully, the striking improved drastically, andI found a rhythm within just a few balls.
Because it was the first time I was using the TRS Slider, I thought it would be a good idea to hit more balls to give me a bigger data set, so I ended up hitting 23 in total.
Performance results: The data that blew me away
Using the Slider, I definitely felt like I was swinging better. My backswing felt shorter and more controlled than usual, and I was hitting the centre of the net much more consistently. But feeling an improvement isn’t the same as there actually being an improvement, so it was time to review the data.
I reviewed the session in the FlightScope app, removed the obvious outliers (shanks and real mishits), and got to work comparing the numbers.
FlightScope Mevo Gen 2 data comparison
Below is my Mevo Gen 2 swing data for 9 shots taken with my 8 iron, with my normal swing whilst not wearing the TRS Slider.
Below is my swing data for 18 shots taken with my 8 iron, with my normal swing whilst wearing the TRS Slider.
Here is a quick comparison of my 9 “normal” golf swing shots compared to the 18 shots whilst wearing the TRS Slider.
- Carry Distance: +1.8 yards
- Lateral Deviation: Reduced by 3.6 yards
- Ball Speed: +1.3 mph
- Spin Rate: +248 rpm
- Club Path: Reduced by 2°
- Angle of Attack: Reduced by 0.5°
In-depth AI review: BadgerAI analysis
To get an even more objective look, I used FlightScope’s BadgerAI tool. This handy tool allowed me to analyse the entire session, including the shots that I deleted. In analysing the 13 “normal” shots and 23 shots wearing the TRS Slider, the improvement became undeniable:
- Carry Distance: +6.6 yards
- Ball Speed: +4.1 mph
- Spin Rate: +689 rpm
- Lateral Accuracy: +7.4 yards (closer to centre)
- Club Path: 70% more neutral (Improved by 1.8°)
- Face-to-Path Control: Improved by 8.9°

8-Iron Performance Analysis: Session 9064200
Comparison: 8i – P770 vs. 8 iron wearing TRS
Conclusion
The 8 iron wearing TRS performed significantly better. The 8 iron wearing TRS is the clear winner based on the data, demonstrating improvements in both distance and consistency.
Why the 8 iron wearing TRS Performed Better
Superior Distance: The TRS club provided an average of 6.6 yards more carry distance (129.9 yds vs. 123.3 yds). This is primarily driven by the 4.1 mph increase in average ball speed (99.0 mph vs. 94.9 mph). Higher ball speed translates directly to more distance.
Tighter Dispersion (Accuracy): * Lateral Consistency: The average lateral distance was much closer to the center line (0 yds) for the TRS club (2.0 yds right) compared to the P770 (9.4 yds right).
Shot Grouping: The standard deviation for both carry distance and lateral distance was lower for the TRS club, indicating a tighter, more consistent grouping of shots. The TRS club is more predictable and reliable.
Better Spin Control: The TRS club produced a higher average spin rate (6,158 rpm vs. 5,469 rpm). For an 8-iron, higher spin is generally desirable as it helps the ball fly higher, stop quicker on the green, and provides more stability in the air.
Consistency: The P770 data shows a very wide range of spin (min 3,385 rpm to max 7,273 rpm), which suggests significant inconsistencies in strike quality, leading to “flier” shots (low spin, low flight) and “ballooning” shots (high spin, high flight). The TRS club’s spin was more tightly grouped, contributing to its better consistency.
Key Takeaways for the P770 Shots
The P770 data shows a few outlier shots with very low spin (e.g., 3,385 rpm, 3,888 rpm) and very high lateral dispersion (e.g., 50.1 yds and 56.4 yds right).
These shots significantly dragged down the average performance and consistency metrics.
This suggests that while the P770 might have a high potential when struck perfectly, it is much less forgiving on mis-hits compared to the TRS club.
Swing Analysis: Mechanics & Delivery
Focusing on Club Path, Angle of Attack (AoA), and Face-to-Path relationship.
Club Path: The Key Difference
The most significant difference between the two sets of shots is your Club Path.
8i – P770 (Average Club Path: -2.9°): This is a moderately strong Out-to-In path. This means the club is traveling across the ball from outside the target line to inside the target line at impact. This path is the primary cause of your fade and slice shot shapes with this club.
8 iron wearing TRS (Average Club Path: -1.1°): This path is much closer to neutral (0°). A path of -1.1° is still slightly out-to-in, but it is 70% closer to the target line than the P770 path. This more neutral path is the main reason you hit far more straight and draw shots with the TRS club.
Conclusion on Path: Your swing is naturally slightly out-to-in, but for some reason (perhaps a change in setup, focus, or the feel of the club), you were able to deliver the TRS club on a much better, more neutral path.
Angle of Attack (AoA): Consistent Steepness
P770 AoA: -5.9°
TRS AoA: -5.3°
Analysis: Both numbers indicate a steep Angle of Attack for an 8-iron. The ideal AoA for a mid-iron is typically between -3.0° and -5.0°. Your AoA is consistently on the steeper side, meaning you are hitting down on the ball quite aggressively.
Impact: A steep AoA can lead to a lower launch angle and higher spin loft (the difference between dynamic loft and AoA), which can sometimes cause the ball to “balloon” or, conversely, produce low-spin “flier” shots if the strike is thin.
Observation: The TRS club had a slightly shallower AoA (-5.3°), which is a minor improvement and contributes to the better overall performance.
Face-to-Path Relationship: The Shot-Shaping Factor
8i – P770 (Average Face-to-Path: 10.9°): This is a massive positive number, meaning the club face was, on average, 10.9° open relative to the path. This is the textbook recipe for a slice or a push-slice. The ball starts left of the target (due to the -2.9° path) and curves violently to the right (due to the 10.9° open face). The extreme outliers (35.5°, 39.6°, 30°) are the shots that resulted in the severe push-slices and the poor lateral dispersion.
8 iron wearing TRS (Average Face-to-Path: 2.0°): This is a much tighter, more controlled number. A 2.0° open face relative to the path will produce a slight fade or a straight shot. When combined with your -1.1° path, the ball starts slightly left and curves slightly right, resulting in a much more manageable shot shape.
Overall Swing Conclusion
The reason the 8 iron wearing TRS performed better is that you were able to:
Neutralize the Path: You reduced your out-to-in path from -2.9° to -1.1°.
Control the Face: You dramatically improved your face control, reducing the Face-to-Path angle from a slicing 10.9° to a manageable 2.0°.
Recommendation: To further improve, focus on maintaining the -1.1° path you achieved with the TRS club and work on shallowing your Angle of Attack slightly to get closer to the -4.0° range.
Final verdict after first use
Based on both the data above and the feel, it’s clear the TRS Slider really does work. I’m genuinely surprised that it made such a positive impact on my swing and ball striking, in just one session, especially without me consciously trying to make any other adjustments to my setup or swing.
I’m excited to continue testing the Slider in preparation for my full TRS Slider review. If these initial positive signs are anything to go by, it’s fair to say the TRS Slider really does live up to the hype.
