I rotate between a '21 Rad MP, a Speed Pro, and the Prestige Tour as my main racquets for hitting and coaching. The Tour is nice, in a lot of ways it feels like a slightly heavier version of the Radical. It has good control, decent feel, it's stable, and it's maneuverable enough that you can really swing out with it and get some good pace. That being said, outside of the additional mass and stability, I find that it doesn't offer much that the Radical doesn't. While the Tour is an 18x19 and the Rad is a 16x19, because the pattern of the Rad is so dense in the middle of the frame, control, spin potential, and launch angle are very similar. The Rad doesn't feel much less stable than the Prestige, despite less weight, and it does feel more maneuverable, so at net I definitely prefer the Rad. The Rad also just feels a little better and crisper. Maybe not as soft, but definitely cleaner. The Radical has more free power as well. Not an insane amount of power, and it's not like the Prestige is underpowered (Head lists both racquets as having the same CPI of 400), but it's still a factor.

I know this is a really loose and wandering overview - if you have any specific questions about the Tour let me know and I can try to speak to those.
