Here's the only way I could get the rope to run against the equalette. 9/10 times, the biners simply righted themselves and all was good. It stuck this way just once. Your picture looks as though the rope ran over both strands of the cord though, which would imply that it got over the top somehow. Said it was hard to see the master point after the rope pulled it tight, so you didn't rap off after setting the anchor right? Just built it, tossed it off, and walked down?
Well shoot dude, glad it didn't burn clear through on ya. I saw the second strand burn too; but couldn't get my cord to reproduce contact with both strands unless I ran the rope entirely over the cord. Coulda been worse.
