North Rib seems to be standard. It's loads of fun and easy to follow. just top out the chute to the climbers left of the Rib proper.
CalicoKat reported to me that the NW ridge jumps between Class 3 and sketchy 4 just before it meets up with the exit chute for the N. Rib.
You'd also add some distance, I don't think it's much but if you are dayhiking this nasty beast every mile counts.
