Hello all, I am a 13 year old tennis player who has used rpm blast at 48lb for a while now and have found it to be nice, but a little harsh on the arm. I have broken them now, and I was wondering what I should get next. I use a full western grip so I'm looking to generate a lot of topsin but I would also like to create a little more depth as well. Could anyone recommend some string setups and tensions? Any responses will be appreciated.
