I'm becoming a Quasi believer. I had Bobby's first pro model and really liked the wood, dims, kicks, and concave. The tail is mellow, which has become more comfortable for me. I've found that exerting more energy/pop on a steeper concave is labourious, and not worth the effort - I can ollie comfortably on a Quasi's mellow tail.
Just bought a proto 8.25 by 31.75 by 14.25. I usually skate boards that are a bit smaller, but the Bobby model had the same dims and I enjoyed it. Once I'm ready to skate the proto, I'll post it in the set-up thread.
