You have heard the arguments about a level nock travel.This is what happens when the cycle is not level.I tried to install a quick tune drop away on my magna tec.The nock tavel is so bad you could not get clearance.I talked with NAP and Hoyt and the verdict was that this type of rest would not work on many types of bows due to the nock travel.I was not a happy hunter!!! I love the bow but it does have nock travel issues.Mine is a Redline HO.
