I tried the V2 based 19t once but I didn't think it was any better then any other 19t. I didn't get a chance to play with timing much though. I really think its hard to beat the C2 motors. The Yok based ones are really good when you find the gear on them. We also have the Atlas based 19t. I've run it some and its a really good motor. I know Brian has done really good using his. Maybe he can post a little more info on how he liked it compared to the C2.
