Good thread insofar as reminding ourselves that those old pins are totally suspect!! Keep a screamer or two on hand at least, for that one pin you know you need, but don't really trust. Ever since a friend easily wiggled out the knifeblade piton that used to be in the potato chip flake not far below the anchor on Broken Sling (which I'd blithely clipped many times, even though there's other gear to be had), revealing the last two inches or so of the blade to be no thicker than tin foil, I've been very wary of Gunks pins!
But I do love those honker angle irons! Especially the shiny new, replacement ones!
we're all living proof that nothing lasts
