Did this first in '89 and probably 20 times since then. Still a tricky lead after all this time!! The key is placing gear in the less positive locks and using the good ones to climb. Of course, I never seem to get this right:(! During one of my early and impressionable ascents, I had Jim Yoder solo up and past me complaining that "he almost greased off down there!" Freaked me out at the time, but I think he was just hamming it up!
