Hello Everyone! I am currently using a Babolat PD GT. I purchased the racquet about 3 months ago and just bought another one this week. I found that when play with the racquet 3 months ago, my arms hurt then it went away after 2 weeks of playing. With the new racquet, same thing happened. I wonder if this is normal? Also, how long does it usually take to adjust to the racquet after it is restrung? I always find myself missing my strokes and play terrible every time the racquet is restrung. P.S. I believe my form is decent. Please helpppp...Thanks!
