Greg, I shot a Carter Lokjaw(nylon connector) and liked it. It just wasn't a good release to use with a loop because of barrel width. I have no problem using my Lil Goose with a loop, but I see that Scott is promoting both the Wildcat and Sabertooth as good releases to use with a string loop.

Personal preference with barrel, rope, or nylon connectors and being comfortable, tho for hunting that dang barrel can get in the way.

Hmm, single caliper or dual caliper.......maybe it doesn't matter.
