and make it harder to prussik or haul out, try untying knot when weighted....
and hang up on absol-fucking-lutely-everything!
I think the idea with knots between 2 on a rope is to also tie into the middle 45 ft of rope. That way each person has a coiled 55-60 ft they can throw down. Obviously the negative would be having to rig prusiks on the free line while hanging.
I first heard of the knots in the rope while in the Alps ski touring. Most of the euro's also carried a couple of ice screws so they could anchor into the sidewall and get situated.
no i read the article, they used the knots to addd friction on the edge of the crevassse... they said like put a butterfly knot every 10 meters or something... theoretically sounds good, but what about the hagups and the near impossibility of self-extraction after riddling the rope with knots?
