In reply to Ron Kenyon: I did the same with 17m a couple of years ago. I'd experimented with 35m but found it a real hassle stopping the tangles.
Had planned to abandon the 17m length tied off to the Pinn chain but decided against littering & investigate the old way of descending short end. The flake has a perfect wee pyramid top for running a rope over but was far more entertaining trying to hold the 6mm on while tying italian hitch with one hand!
Yet to find the balls to downclimb the short side unroped!
