I have to agree with everyone.

My 30yd groups went from 4" to less than 3" when I added a loop.

And as far as wear on the serving goes. I can wear out 2 servings on a string before the string is worn out, so there is a lot of benefit there.

I have been shooting a loop for several years and I have never had one break or fail. I always have mine installed by my bow tech.
