I've tried all but the TRice. I highly favor the Machete. The Slayblade's 0 camber is cool and all, but it just isn't as fun as the Machete. If you can handle fast boards and love to bomb down runs, the Machete will do the job. This board had great edge to edge control and had 0 chatter when bombing steep, icy runs. It also had a very satisfying amount of pop. Popping off natural features was a joy.
I hear great things about the TRice though. If I needed another all-mountain board, the Machete would be it.
