In reply to Tom Randall - Lattice Training:
"He would have roped up for considerably more than just those 2 pitches. It's often the opinion you'd get watch vids, reading websites, but not the true story."
I think you need to read carefully, he did NOT rope up for the changing corners pitch!!
He did rope up for the great roof and climbed like a rope soloer, thats it.
"He brought about a 30 ft cord on Half Dome and he brought a full 60 meter rope on The Nose, only used it getting to boot, for the king swing, and on the great roof."
