I actually think the smart grip feels pretty good for my 2hbh, although I have only held it in a store. Youtek (3D0)? would be awesome if that stuff actually works. I feel bad for the marketing VP in tennis racket companies who have to come up with new BS every 2 years and have to claim it is better! All they did was changing the stiffness, balance, SW, string pattern, and weight back and forth to create a "new feel".
