He said he moved the belayer, which implies a reidirect to me. But redirection is a different argument.
The folks who climb with me will testify that I haven't commented even once about their anchors, whether constructed with the rope, stretchy cordalettes, stiff cordalettes, or a combination of some or all of these.
From what I hear, this is true, and kudos to you for it. As our common friend once said to someone we were about to share a rap with: I don't care what knot we use as long as we don't have to talk about it.
I just explained why a person might choose to use a stretchy cordalette.
Which is actually the first useful piece of advice I've managed to glean from all of this. As you know, I object to one method being debunked without a better one being provided and I've yet to hear why any non-lette option is better than any-lette option (or even convincingly why one lette option is better than another). If a stretchy lette can really make a difference, well, that's an easy substitution. Are you saying that simply nylon vs. tech cord is really going to make a measurable difference in stretch for the distances involved? I don't like the bulkiness of nylon (why all of us who choose tech do, I'm sure) but I need a new a cordelette and I could perhaps be convinced.
