I know I'll get used to it in due time. I have always used kevlar in my racquets and have just recently switched to pro poly plasma (used it in my Tour 8 also) and I string it at the max tension, 60lbs, in my Tour 10 Gen II's, so there's not much room to move there. I think some of you may be right about the contact point, maybe I am catching the ball just a little bit late with a heavier racquet.
AAAA, I switched because I was starting to have trouble keeping balls in with the Tour 8 when playing hard hitters. I was just recently bumped to 5.0 and play heavy hitters on a regular basis now. I used to use the old POG oversize and probably never should have switched to a lighter stiffer racquet (midsize, yes) but not lighter and stiffer. I also thought the switch would benefit me in the long-run. I feel it has already helped me with my serve and my volleys. I feel like I don't have to do as much with the racquet because of the extra weight. I used to have a tendency to swing a little at my volleys because I felt like I had to generate pace. With a heavier more flexible racquet I don't have to swing. The mass of the racquet seems to generate the additional pace/punch that I need.
Michael, I have ordered some Signum Megaforce strings and will see if that helps a little bit. I've heard these strings are supposed to be a little stiffer than the pro poly plasma so that might just be the ticket. Thanks for the input.
I've heard it takes someone about 4-6 weeks of playing with a new racquet to really get accustomed to it so I'll have to keep everyone posted. Thanks for the replies.
