Did he get back to you with batch or production run numbers (wonky v.s. new improved) - I could be wrong but that should be available as part of CE cert process I think. Personally a Saturday project today was to cut out the ISC triple snaps I had and render them unserviceable (and a buncha funny shapes) with a sledge (and a beer). Once you introduce doubt into the system and yet another thing to always have to check up on, I check out of stuff like this. Check my prussik cord before I tie up, but never had it not work if it gets clanked against a trunk . . . so in my risk matrix, not worth the anxiety if it's gonna be fussier than a triple locking biner. Some of the above experience makes me nervous, esp. if I can't ID new stuff from old stuff I might have. Back to ISC doubles for me.
