I might have one, I'm not sure. If I do I can weigh one and compare it to a nock. If that is the case I would just use a brass nock, or better yet a tied on nock.
I wouldn't use something like this to cure peep roll over. If you are having problems with this just get your string adjusted so the peep rolls over to where you want it when you draw the bow back. Might only need a half a turn added or taken out to get it right. If it still isn't cosistant you need a new/better string and adding this thing may not solve your problem.
I used to use the ultra nock XL and the concept is similar. P I A to set up initially. With a loop you just turn it, you don't need to loosen any tiny screws and worry about the thing flying off while you are shooting it.
My honest advice, I would give the loop another chance and shoot it long enough to get used to it. Your wrist release may be adjusted too long, or maybe the loop was too long. As long as all your reference points for the string are good where you anchor on your face shouldn't make a huge deal, unless you are bit long on draw length to begin with.
I do see where you are coming from though, for a hunting only rig shooting off the string is sort of stupid simple. I don't even use a peep sight for hunting anymore. Solves that problem right there doesn't it
.
These are only my opinions though, nothing more. I am surprised you haven't gotten more responses.
