I’ve played the game of squash on and off for about 18 years now. I’ve probably played with dozens of different rackets. Different materials, different composites, different grips, different strings, and different shaped rackets. So, I do have a few opinions when it comes to rackets.
For the majority of players any of the top brands like Dunlop, Black Knight, Wilson, Technifibre, Head, Prince, Manta, or Karakal all manufacturer an appropriate racket. I wouldn’t get too hung up on brand name. Unless, your one of the top 200 players on the PSA tour, there’s really no need to spend more than a hundred dollars for a racket.
What matters the most, is that a racket feels good to you. Weight and stiffness, are probably the two most important features here. Also, bear in mind, that a lighter racket, with good stiffness, and reduced vibrations is less likely to cause repetitive strain type injuries over the years.
The other thing to keep in mind, is that once you have a racket you like, be sure to own at least 2 of them. That way, when one breaks, or needs to be restrung, your not stuck playing with a completely different racket. I actually have 4 rackets in my squash bag at the moment, with one more on order. Only on of those current 4 do I consider playable at the moment. It’s a Wilson N145, the same as the one I have on order.
The oldest of those rackets (a Slazenger) has a hairline stress crack, and will probably go any time. It’s like 10 years old, so it doesn’t really owe me anything. The remaining two need restringing, and I’m not sure they’re worth being restrung. One is an Unsquashable, that I won at a tournament, and have never been all that attached to. The last one is a Black Knight Viper, that is pretty old as well, and will probably break as soon as I get it restrung. So, I haven’t.
