They open a little differently. The guy at Kitesurfari said: "The Ronstan Shackle would occasionally catch
the chicken loop, preventing it from releasing fully." I have heard it both ways now. I will just keep my gear clean and hope it works when called upon. (Ronston is on the bottom)
I did hook into my harness for the first time today. Although I am stil awaiting the pully and the shackle I figured what the heck. *shrugs* Anyway, it made my day of flying much more enjoyable. I can't do that to often though. I already wore the anodizing off the caribiner.
