I've used very size racket up to 110 ( was a big fan of the pog and rad os), everything from old school players rackets to pure drives and such. I can play a pretty reasonable game with any of them. But some I enjoy playing with, and with some, it just feels like a job.
I play great with a pure drive, and, if I were on the pro tour, it's probably what I'd have to play with, because I can win with it. But the truth of it is, the feeling of hitting the ball with it is a bit like kissing through a screen door.
And at 58, there's very little chance I'm going on the tour, so I play with a racket that I enjoy the sensation of hitting the ball with, the old school prestige mid, which, for me, produces a lovely feeling of the racket just folding around the ball and crushing it to its target. Oh, and I happen to play just as well with it as anything else, assuming I'm watching the ball that day
It's hard to describe, it's a bit like trying to tell someone about the sensation of eating potato chips to someone who never has: that lovely crisp sensation of a properly weighted set of graphite and strings crashing into a tennis ball. I find it to be the most important reason to play tennis, to just enjoy the sensation of hitting the ball. And for me, my 90 does that the best.
