In the early 80's when I shot a wheel bow I used a Hoyt pro-rest and shot vanes. They shot good.
Like James, I am shooting bows in the low to mid 40's and don't want to waste any energy on wobbling arrows. I have shot off the shelf for years but have to continually fuss with it to get good arrows flight. Just last week I put a rest back on an old Shakespeare Kaibab and it made a world of difference. Day before yesterday I put a trimmed brush rest on my Bob Lee and now it shoots 2016, 1916, LW, RW, cock feather in, or cock feather out equally well. I used to have to worry about getting the feathers indexed just right to clear the shelf..Now I just shoot.
