So I have a Prince Hybrid Hornet OS weighing 10.1 oz which is something that I won't use long term. I have tennis elbow which I believe is a result from using full polyester strings. Therefore, I am looking to get a racket that is somewhat heavier and better for the arm, so I don't have to produce all the pace, however, I don't want something too heavy, which I can't handle. Let me say though, I am not well-built. So here are the rackets that I plan to demo: Yonex RQ iS 2 Wilson K-Factor Six-One Team Dunlop Aerogel 3Hundred Tour Dunlop Aerogel 5Hundred Tour Babolat AeroPro Drive I am basically looking for something 10.6-11.2. I won't be able to demo until another month since my physical therapist wants me to start trying a heavier racket after I build up my strength. Before I was told by my physical therapist not to try a heavier racket yet, I tried out the Yonex RQ iS 2 with Yonex synthetic gut strings; that racket really increased my pace but I was able to get no top spin. Any possible reason for that. So please tell me which of those rackets are best for people will tennis elbow(I will be using hybrid strings from now) and gives a good amount of top spin and pace. Thanks in advance.
