rope loops are easy to tie on, and easy to learn to do it. I've never shot without one. I did, however, try a metal loop a couple of years ago, and twice had it hang on my release in about 20 shots, which took me by surpirse. I use a scott release, and for some reason when I released with the metal loop, it didn't release when it was suppose to a couple of times. I took it off the same day that I put it on, and tied a new rope on and have never looked back.
