The last thing you want to add to your string is a metal loop, unless you are looking for more trouble than you can handle. Some might argue the point but it is absolutely one of the worst things you can do with a bow.
ive used them for over 10 years as well as my 2 brothers. not a single problem.they actually get smoother with age.it provides a way better solid feel when you lock up with the release. i tied a loop on for a couple weeks and then took it off. in archery its whatever works for an individual. ive seen a bunch of failed loops through the years but my ultra nock keeps working. its been on my current hunting bow since 2000 and it was on my bow before that.
As you just said. To each his own and I have no problems with that. To that end I use neither a string loop nor a metal loop. I have used a rope release (target style) for about 30 years now. Have used caliper style and/or wrist straps and always come back to my Cascade.
There are so many disadvantages vs advantages to using a metal loop that I won't waste my time typing. However, there are a few safety issues I saw when working in a shop. There were a couple bows brought in with metal loops where the string broke at the top of the metal loop. And I mean snapped. It's due to the sharp angle and constantkink at that point. Strings aren't meant to be subjected to such sharp bends all the time. This is made even worse with today's ultra short bows and longer draw lengths.
