I have setup a lot of QAD's and when they work, they are a nice rest if you prefer full containment.
The issues with clearance occur way to often to suit me and in a couple of cases I could not solve the problem. Even after talking to QAD they had No solution except to raise the nock point ridiculously high and jump the arrow over the rest.
No Thanks!
That's the reason I think the Limb Driver is the best dropaway on the market. No setup issues, No timing issues, and No resulting clearance issues. It simply works!
