so you weren't having arm issues before you switched from the pd? Why did you switch racquets then? If I were coaching you I would not have done that unless there was a good reason. Most competitive players do not like to switch and have a setup they are not used to in a match. It sounds like your arm was ok before you switched to something else. I see plenty of good competitive juniors using the babolat. I doubt they are all having arm problems. You need to demo it .
