climby: I climbed it MANY years ago. Here's what I recall...
My buddy and I were up near the summit, and the 4th class part was to our left, and on that section was a guide and his client. We were attempting to climb it without technical gear -- all third class. We were hunting around for the route to climb, and the guide gave us a big hint: He said you might want to move to your right a little. We did that, and found the correct route to the summit. We then descended the same way, and I don't recall it being that difficult.
The guide and his client used his ropes, etc, and rappelled down the face as we watched with envy.
Good luck! and let us know how it goes.
