How can this be? Blazers are supposed to work well with the biscuits.
I've heard of some that don't fit a Hoyt so that may narrow things down a bit. I have a GKF Infinity drop. It is the infinity rest made into a drop and can be used as a springy rest if so desired and comes with 4 different launchers. Other than a design flaw it is built like a tank, and very micro adjustable. The problem is the spring and the tolerances of it with it's housing, it rattles on the shot giving noise and vibration. I fixed it by making a shim out of a dura vane. Other than that I don't think there is a better one. Don't be fooled into believing the service is 100% satisfaction from GKF. It will cost you more if there is a problem. I have experienced the real deal and can say from experience that GKF doesn't measure up. Persistence will get you about 80%.
The fact that it's two rests in one is a real plus. Mine cost around $130.
