That is an interesting thought. A hole through and basically doing it like a dyneema wishbone through the muzzle. Tie in loops like Kevin at Hammerhead does, line through muzzle and locking knot it...

Has that been done?

EDIT: Ah, did not read Pastor's post throughly, I guess it has been. I like the idea. You could top mount the bands, drill down from top to bottom so your passing the line down and under the muzzle and back up through a hole on the other side. Not sure it applies here with the enclosed track, but I guess it could.
