I finally got off the shelf last week, and I will NEVER go back down. Instant improvement in group size. I can now run a 1/4" high nock, instead of the 5/8" high nock that was required before with shelf shooting, to prevent upward fish tail flight. And the arrow no longer looks like a NHRA funny car on the string because of that 5/8" nock.
Best thing I ever did. I went with the Hoyt Super Rest. $ 2.50 and the target guys say it has won many FITA tournaments.
I did the stik under the rug thing, leather shoe lace, leather pad, and I forget what else. It made no difference for mine. Still had to run that high nock. Once I went to the Hoyt Super Rest , and 1/4" nock, its on now.
The Hoyt Super Rest has a built in springy side plate that acts like a cushion. And it comes with a two sided stik on spacer for someone with a cut past center bow like ILF, but for wood trad bows you won't need that.
