Has anyone used (or heard of)a Schaffer drop away rest? I hadn't even heard of them until a week or two ago, but from the little I've heard, they are supposed to bea good rest. Any other opinions?

Yes, they are vey highly rated and well made. I just ordered one for my new Trykon.

Do they have a website?

There ya go.

Neg- Takes more pressure to get the rest up compared to some other drop away rests that I have shot. Also has a lot of different adjustment screws to do a job that only needs a few. Also, I dont like the way the cord fits into the rest. I had it set up to go up at the very end of the cycle as they recommend. Cord would become worn and fray. Pos- Easy to access spring. Built like a tank.
Shot it for a few months and went back to my trophy taker.

Thanks for the info...I'm trying to decide on a rest for my new bow. I might give a Schaffer a try.
