We brought cams up to a #3, mostly singles but doubles in a few sizes, especially in the smaller range. Tony is a strong climber and didn't mind running things out, so if I had been leading I probably would have taken a larger rack, but still mostly bringing extras in the small cams range.
The Lower Buttress is in the shade most of the day. Perhaps in summer days you will get a bit of sunshine, but expect shaded, cold climbing until one reached the crest of the Lower Buttress. From there the route stays mostly in the sun.
As if the Grade V designation isn't enough of a hint, this is a long route, so start early, move fast, and simul or solo most of the pitches above P3. Also, the Middle Buttress is much larger and takes more time to cross than the topos lead one to believe, so don't get casual after the Lower Buttress like we did!
When simul-climbing the Lower Buttress, shorten the rope if simul-climbing before the chimney. After the chimney, 60m is fine and you can simul to the base of the Middle Buttress (nice sunny lunch/nap bench). Shorten the rope to 30m for simul-climbing on the Middle Buttress - 60m is too long and drag will eat you up and force some belays.
The rappels can all be downclimbed at 5.6 or less, with reasonably solid rock - however routefinding to do so is tricky if you're not used to simul-climbing complex alpine ridges.
I only know of two topos for this route - the one from Moynier & Fiddler's great guidebook, "Climbing California's High Sierra: The Classic Climbs on Rock and Ice", and the one from Peter Croft's guidebook "The Good, The Great, and the Awesome". While Croft's topo is less detailed and clean, I'd say it is the more accurate and informative topo and does not mislead one into thinking the simul-climbing distances are shorter than they are. We didn't bring that one along but looking at it after the climb, I wish we had!
Looking on SuperTopo, it appears that Chris McNamara and Brock Wagstaff have basically combined and improved upon these two topos. So the best and most complete one I've seen is found at the link below:

Only suggestion is on P14, you can also go left of the crest on cl. 3-5, and it misses the 5.10 & 5.8 variations that finish on the upper buttress. Also, I thought P2 was harder than 5.8 (maybe because my hands were cold and I was tired from the long pitch?), P7 was easier than 5.8, and on P6, climbing out on the face is optional and for knowing the technique the chimney was more like 5.6-5.7, including the finish if you stay in the crack.
