Yah know I was wondering that as well couldn't you hook up a rope wrench to it and climb SRT? I mean it functions the same as a regular eye to eye Prusik within reason of coarse, but wouldn't it work the same I had a gen 1 zig zag and I loved every minute, and never hand a issue with side loading a carabiner, I feel that the climber should be paying close attention to every aspect of there climbing apparatus, anytime I would sit or put any weight into my system even with a lanyard I checked just seemed like common sense to me to check
My motto: check, double check, and check it again,
