Actually, I have heard that the Dayan 2x2 is pretty good (after all, it is made from a Zhanchi) so I might go with that. As for the 3x3, I have been borrowing a friend's Guhong (that's what I planned to use at the comp) and I'm quite used to it and like it, but I just hate all the pops. I was going to put all of the torpedoes from my stickerless zhanchi into the edges, but it turns out that they don't fit. Really, I can go with any style, probably, as long as it's very fast; the Guhong doesn't have such of a nice feel as my Zhanchi, but the Guhong goes faster, for me. Guhong is scratchy, and Zhanchi is smoother (at least, the stickerless is). So speed is my priority, I guess; I don't really care about the feel.
Dayan is awesome, go for that with 2x2. Try a Moyu aolong for a 3x3.
