I had the Quality Archery Designs drop away, it looks just like the Rip Cord. Froze up on me when it got cold (and it was a new rest). Switched to Trophy Taker, don't dare to switch back- Simple is better in my instance.
Oh yeah, it froze up when I had a 180" deer at 8 yards, I promise that's when it happened AND the 1st time I had noticed it, of course it would go like that right!??!?
