So far I love it.. Getting it on and off the rope is effortless..Slack falls through it better than any footie I have used..So far zero issues with is not grabbing, and as you said it has virtually no negative impact on your climbing lines.. The only negative I can report so far is that it is a little difficult to get tight on your foot when new, but as the clasp has broken in that problem is quickly disappearing.I still haven't picked one of those up, yet... been waiting for you to do it so I can get your Shiny Object review...
I want one because it almost HAS to be better for the rope... but... does it perform as you expected? Fall out, too much? Not grab when it should? Any deal breakers I should know about before I buy one, so I don't have to call you names and make fun of you? Well, ok, I'm going to do that anyway... but still... I value your opinion on subjects not related to sex and farm animals.
I like it enough that I have been thinking about how one could be attached to a gaff..
