I've got a Bear TRX - and I know for a fact the draw length is NOT too long -that's a wrist stinger when it's backed off to 65 lbs. It's not bad when it's cranked down to 70. At 6 3/4" brace, I just don't think there's enough tension on the string to limit the forward string travel on the shot.It'd probably be a good candidate for one of those string suppressor doodads. Not saying that's the issue with yours, but I'm pretty sure that's what's going on with mine.

Actually, my bow came with a string suppressor type thing that had the stopper combined with the cable slide. Wierd deal! I replaced it with a standard cable slide at once. Maybe I should investigate that thing a little more.

Don't worry about the loop.Simply use good quality loop material,keep it waxed, run a Q-tip or cotton ball over and around the jaws on your release every so oftento make sure you don't have any damage or burrs, replace the loop about once a year - your major pre-hunting seasontune up and sight in is the perfect time to do it -and you'll never break one.

The only people that break them are the ones who try to push them long after they should have been replaced. The only people that have the knots come undone are the ones who screwed up tying them in the first place. Loops are perfectly safe to use.
