balanced at impact
Go to their website and a short video explains it.
For a long time I thought, it's just marketing.
I was fitted for one, still didn't understand or focus on the face balanced at impact part. More testing and reflection on the fitting process, and yep, I believe it.
The RST part eliminates the ball position variation aspect, critical to putting the ball on the same path more consistently, roll aim, increases confidence etc.. Boom, ball is in the same spot in your stance every time.
I tried every reason to justify a different brand or style of putter over several years so I could buy brand X with model Y.......couldn't do it.
Not for everyone of course.
The online fitting specs (custom for length, lie and weight) matched my in person fitted specs.
The most customer oriented company.......period.....before AND after you purchase.
Tons more I can say about the process, my personal journey and experience with the company.
Just ask here or offline.
