In reply to mmmhumous:
> Pretty much where this post stemmed from...the idea that IF you're both on top of the ridge AND decided that runners are overrated AND the 'non faller' has cat like reflexes and nerves of steel. They catch the fall.... now what?
Yeah, I stop and ask questions well before the "now what" stage. Such as "why are we roped together?". If the answer is "in case one of us falls" then place runners (or loop over a spike, or belay, or whatever).
Your question still works if you do place runners, one falling may cause the other to slip and fall down the other side, so self-rescue is still required, just not the cat-like reflexes and nerves of steel.
Just my opinion of course, and quite a boring one by the looks of things.
