Stump,the biggest reason people use them is accuracy.Look at tournament shooters,almost all of them use them.


What makes them more accurate is they allow for the most precise draw length adjustments and the absolute most forgiving release available.No torque from a release is crutial to downrange accuracy and draw length being precise is also imperative to accuracy.


This is not to say that shooting off the string isn't accurate but when you start splitting hairs,a loop has more advantages than shooting off a string.



I do use one and with a release made for a loop,I can hook it up as quick or quicker than directly to the string.

I did have one fail once in thousands upon thousands of shots but like said many times,it was my fault.I didn't burn the end properly and it pulled through after about 100 shots.That was a ccouple years ago.Once in 6-7 years and it was my fault.
