I agree with most of this -- amazing feel and not as sluggish as the blade 18/20.I've just tried the TF40 RS 305 and 315 and i've been hitting with them for a week now. Both racquets felt the same except that the 315 was not as stable as the 305. So decided to focus on the 305 which the demo racquet came as 335 gm strung ( TF razor code) and with a wilson pro overgrip. The racquet has an amazing feel and comfort although razor code is not my favourite string by any means, it felt great. What surprised the most is the swing speed esp. from the baseline. It swings faster than what the balance point would suggest esp. compared to the blades which feel a bit sluggish and harder to swing. I think TF has done something good with the frame design. I am generally a flat hitter but i felt a little bit of lack of ball rotation coming from the racquet which it didn't bother me much, also i am sure i can get better spin with strings like 4G rough or volkl cyclone. Overall, the frame has a good balance between power and control, very solid, amazing feel, amazing comfort (best i've tried so far), manuevarability is not bad at all, spin (string sensitive) have to select the right string to get the spin I need.
