I started playing with the PS and the reason I switched was golfer's elbow. I knew the biggest culprit in my issues was/is my technique cuz I learned on my own w/o training but didn't wanna risk a long-term injury until I fixed my strokes.
Blade 18x20 was great in that regard. Super comfortable, great backhand, control etc but it was too head heavy, needed better timing and I wasn't (maybe still aren't) as good of a player for that stick.
I really didn't wanna like the Radical cuz of the color but it was great. Maybe a tad under-powered on my backhand but still..Yet alas, I experienced wrist pain after a while with it, especially against heavy hitters
Tried a lot of different rackets for testing in the meantime (over 30 x for sure) including Ezone, Vcore Pro, Vcore98 etc but ended up with TF40 315. Still very happy with it.
It feel more comfortable than the stiffness rating would indicate and there's no feature of it that I don't like
Sorry for the text wall
