Okay, this whole thread is interesting, and certainly relevant to the
list, but I have one question: It seems that some concerns are being
taken a bit too far (IMHO). I mean, "violating the integrity of the
webbing with a hole"??? Does anyone out there seriously put that much
stress on their crotch strap? Did I miss something about wearing a
protective cup while diving? Seems to me, if there's that much stress
going on down there, something far more valuable than one's harness is
seriously at risk!
Just my two bits worth!
