A little intro to myself. I'm currently a junior tennis player in the middle of the college recruiting process. I'm 16 and a half and my game style is primarily a baseliner who likes to work the point. I don't really have a #1 weapon, although my forehand will be the shot that gives me a few winners or cause some errors from the opponent. I hit more of a flatter ball than a spinny ball, although I wouldn't say my shots are like drives, just a bit flatter than spinny. My serve is an area of my game I need to improve on, especially with the toss and motion. My net game is average, I have good hands, but I don't volley well when I am transitioning to the net from the baseline. So here is the problem. Lately I've had some issue with my shoulder/arm. Sometimes I feel like I have a dead arm and there are others when my shoulder gives me a sharp pain. Rubbing any part of the area causes me to feel pain. I've looked into whether my game could be causing my injury, but I've had the same style of playing for my whole life and I haven't had any problem with the arm/shoulder until now. Now I am starting to look into my choice of racquet as a possible solution to my arm troubles. At first, I thought it was possible the balance and swing weight that could have been the issue. The racquet that gave me initial trouble with the arm was the Tecnifibre 305 VO2 Max. The weight isn't very heavy 11.3 oz, especially with the Flexpoint Prestige MP (12 oz), being a previous racquet of mine, however I thought the swingweight at 325-330, and the balance at 6 pts HL were the issue. So I decided to use the Yonex V Core 98D. At the same balance and weight, (11.3), I thought that the huge difference in SW (309), would benefit and erase any issues with the arm/shoulder. However, I was wrong and I continue to feel pain in the arm/shoulder. I've finally looked at another spec that is consistent with the 2 previous sticks I've used.. Stiffness. The Tecnifibre was at 69 and the Yonex at 65, however the Yonex racquet feels stiffer due to the technology they added at the throat to increase stiffness. I find it very ironic that as I've switched sticks into the lighter weight category, I've started to develop arm and shoulder trouble. Can anyone validate the stiffness of my sticks as a possible reason for my troubles lately? This is my brief racquet history and whether they gave me any issues with the body. Head FXP Prestige MP (no issues, whatsoever).. which is quite odd because this is a relatively stiff racquet. Possibly because when I was younger, I didn't hit with the same force? Wilson K Blade 98 (no issues), stiff, yes.. but apparently not enough to cause any issues with the arm/shoulder Tecnifibre 305 Vo2 Max.. using this stick, issues started to arise. Arm and shoulder pain..intensifies when I'm deeper in a rally or over a long match. Yonex V Core 98 d (current stick).. continuing pain. Another stiff racquet. Possibly even stiffer than my Vo2 Max although it is measured at 65 stiffness. So my question is which racquets should I possibly look at? I'm addicted to a stiff feeling racquet, but I know that it might be the reason for my injuries lately. I want to transition to possibly a softer racquet, but not too soft where I won't be able to adjust. Some softer racquets I've tried in the past are.. 1) YTK Prestige MP (Never got along with it for some reason), although I'm willing to retry. Some racquets that are in my mind that I want to try are 1) Babolat Pure Storm GT 2) Babolat Pure Storm Tour GT If anyone has any insight or can help I'd appreciate it. Thanks for reading.
