RE: Accu-wheel or command cam?
I'm assuming Hoyt is refusing to sell you Cam 1/2 because you're upgrading an older model... I've danced that little waltz with them before.
The Accuwheel has round wheel feel with the performance of a mild cam. It has a wide valley and a very soft wall. Excellent fingers shootin' wheel but I prefer a hard wall for shooting release. It is NOT a super speedy setup, but it's very accurate and very quiet.
The later version Command Cam is a good, high performance hard cam with a long dwell and steep drop into a short valley with a hard wall. Good for both fingers and release. Excellent speed, good accuracy but is a bit noisier than the Accuwheel.
There are times I wish I'd gone for the Command Cams instead of the Accuwheels. I like the wheels though.
