I found nuts and hexes to be pretty useless on this climb. Having a lot of cams of various sizes can be helpful for setting marginal pro in flaring cracks or making anchor belays in the wide cracks along the dihedrals and roofs.
If you head directly up the smooth face just to the right of the chute that heads up from the slab's lowest point, you can reach a tree with slings (5.4, ca. 160 ft).
From here, if you head to the dihedral to the right, it offers more place for pro and has a level spot for a gear anchor. (5.5)
Above this is the large ledge with a huge tree that makes a nice belay ledge (5.5 left of the dihedral, 3rd class on top of the dihedral). I never saw the aforementioned bolts here.
Beyond this is a large open face that likely requires a little simul-climbing (5.4 to easy 4th). If you can reach the roof above, there is a tree growing out of it that has some rap slings and makes a good anchor.
Heading up and left w/ a little simul-climbing (cl. 4) is another good belay ledge w/ a good tree anchor.
Beyond this we pretty much simul-climbed & free soloed the slab.
From the top of the west slab, scramble east up the ridge (fun cl. 3-4) until you meet up with the West Ridge route. From here you can either descend the ridge, descend the North Face Trail or climb to the north summit, from where you can traverse to the south summit and descend the main trail.
