the babolat pc standard gives me a huge pop on my serve (4.5 and 5.0 players miss or give weak returns). its the first raquet that i've used that gives me the feeling of being able to crack the whip on he ball during a serve. however it is not my favorite for groundies. The other raquets i've tried yonex mp tour 90, lm prestige, are my two favorites. However i can't get that pop like i can on the babolat pc standard on my serve. the difference is huge. i suspect it is a weight or balance issue. i'd like to better undestand the difference. has anyone else experienced this?
