So I have been playing with a full setup of sonic pro on my youtek prestige pro for about a year now, and I love it. Now that I am teaching full time, I decided to try a hybrid to give my arm a rest as I am on the court 40+ hours a week. I normally sting my racquet at 56 pounds with the sonic pro, so I decided to stick some sensation in the crosses at 58 pounds. It feels completly different. I thought that it would just soften up the string bed a bit, but it gives me a totally different hit now. I hit wiht heavy topspin on both sides, and with this hybrid, I don't feel like I get much ball bite as all. Do you suppose this is because I switched from full poly to hybrid, or did I just use the wrong cross string? Trying to get some input before I go and start spending crazy money on different strings to experiment with. Is the difference between full poly and a hybrid setup like the one i mentioned suppose to be THAT much different?
