Odyssey Aitken signatures on the bmx's and fixed gear (when I feel like going scenester-style with flat bars). They're like a classic mushroom grip but the thickness sort of tapers to fit your hand better. Mmm.

ODI Ruffian Lock-ons on the mountain bikes though. Mmm as well.

Ouries are alright, but even with gloves, I find them slippery when wet. They also get torn up on the ends too easy on the mtb's from hitting trees and crashing. I like a quill-type plastic/metal end plug like on ODI lock-ons or most bmx grips.
