I've primarily used APC and Master Airscrew props in the past. The evolution props are a bit cheaper and are crowding out the others at my LHS. I bought one to try but I haven't flown with it yet.

I bought a 12x8 and it looks lovely. No excess mold/crap to sand off and perfectly balanced. The blades are about as stiff as an APC. I'll have to flyit to be sure but at this point I'm impressed.
