I never had one till this year, I have only about 50 shots with my bow since it came back with a bunch of new stuff. I have some getting used to the loop. my draw is a little longer and I am teaching my self to compensate for the extra length. I also have tried to put the release on the string a couple of times after 17 years of habit. if your going with one like me for the first time, do it soon so you can get used to it. good luck
