I really don't feel that metal loops have any advantages over shooting off the string with a release. I would say the same, with less certainty with regard to string loops. The only advantage a metal loop has over a string loop is less chance of failure. I haven't, for instance shot the TRU metal loop, but all their stuff is really well made, and screw attacheable. I can't see them leaving themselves open to leagal attack by making a product that would break. I haven't had a loop pull off a string after it was properly tightened, but I can easily see how it could happen, particularly to those who are not do it yourself or knot oriented. I use standard loops when I use them at all, but I conceed that the catfish loop (lots of strands of serving wrapped and whipped around the string to form a loop) should be bullet proof.

Anybody out there who attends the large shoots have any idea what the big time pros are using these days? There are at least 5 options: Standard loops; loops tied in weird places, like under a nocked arrow; releases with ropes; releases on the string; misc. stuff like TRU balls (Tom Crowe) or metal loops or whatever.
