Be aware that the Bitz left and right helical clamps ARE NOT mirror images of each other. The left clamp has a 15 degree helical and the right clamp has 11 degree helical. The right clamp is easier to use with prong arrow rests with a set amount of clearance between them.

Any special reason you like left twist? Just curious because most prefer a right twist because it always will tighten up your field points- a left twist will always try and "unscrew" your points.
