Another thing that came to mind the other day at the wall...when I was taught the dogma was that you A) always tie in directly to your harness...not to the belay loop and B) when belaying, put the biner through the tie-ins, not the belay loop. (B) has always ALWAYS bothered me...why have this loop there if nothing is ever tied in to it? Is it just for looks? So the other day at the wall I saw, for the first time, a guy on the wall and instead of being tied in to his harness, his rope was tied in on a locking biner through the belay loop. The thought of that scares me...but it made me rethink (B)...why don't folks clip into the belay loop and belay from there? It seems like it'd work fine...
