It's kinda like this. I currently play with the C-10 pro and like everything about the racket except its maneuverability and powerlevel. Ever since I got moved up to the 4.0 level my serve doesn't seem to be that much of a factor as it was at 3.5 as almost every one can handle a kick serve reasonably well. Besides every now and then I find my self being late on volleys and return of serve. I know I should stick to this racket and improve my strokes and foot work etc. But I don't have the time to play more than twice a week, and that too is in a league. With that in mind I need to be competitive with the 4.0 guys without investing time in practice. I have a spin serve for both first and second, kinda like Rafter as I get about 60-70% first serves in. After about a set of play the swing weight of the C-10 starts taking its toll. Also, while playing at the net in doubles I have missed several volleys during fast exchanges when I get to the ball a tad bit late. A slightly lighter racket with more power will solve both problems. I have tried the Diablo MP, which I liked some, but I find its power level to be almost the same as my C-10 if not lower. If I can keep the beam width, swing wt and flex of the diablo with the power level of the Babolat PD standard that would be my perfect stick. So I ask you my tennis brethren to recommend any wands which have beamwidth under 22mm and compare in power level to the Bab-PD, reasonably flexible, and between 11 and 11.5 oz strung.
