I went out to hit this morning, and after about 1 hour of play my arm started to hurt. I felt pain from my right arm's deltoids/ biceps. i would feel the pain every time i swinged making my shots very inconsistant. my racket and string setup is as it says on my sig. Babolat revenge is realy stiff as some say. some people on the forum asked me if i had gotten pain in my arm. i didn't think i would get arm pain because of my strings. any suggestions? i would still like to keep babolat revenge strings and maybe hybrid it with a synthetics on the cross in the future my choices are very limited to babolat, wilson,luxilon and prince strings. i could also get gosen micro 16 from my stringer. is 18g revenge on mains and 16g gosen micro on cross a good idea? i want my strings have alot of feel and last just as long. on a side note: cross strings top layer has been scratched into.
