I just got a 4D 200 Tour to play with and am really liking it. Allows you to hit a heavy ball with a lot of control. My serve speed jumped up a notch from the Prince Ignite racquet I was using before, and it is a lot more arm-friendly than the Ignite as well. Considering the prices at the moment, this racquet is a steal. The only drawback so far is that it is a little tougher to generate racquet head speed, as I am used to a more head light balance. I am going to try to get used to it, and if I can't, I will modify it some to make it more head light. Overall, a great stick though. I have it strung with Wilson NXT Tour 17g. at 58 lbs. Can't wait to get my normal gut/poly hybrid in this racquet.
