Im currently using the flexpoint radical, but i only have one of it. I then found out that it is now discontinued (anyone know why exactly?) and I thought that this would be a good time to change racquets. Ive hit with the kFactor 6.1 for just a few minutes so i didnt come up with a solid opinion, but it seemed to be a solid racquet feeling a bit like the Head rackets... like rock solid and classic feel... I tried the Pure Drive babolats but they seemed to have too much power with too little control compared to what im used to so im ruling that out... My friend has one of those Nadal Babolats so I might try that out... My problem is I make a bit too many unforced errors hitting the ball a bit too long, but sometimes my groundstrokes also dont have enough power and land near the service line... What racquets do you think would fit me most out of those... and for the kFactor, the 16x18 or the 18x20?
