Hi Bob,
Sorry I can't help you out with Ouray; After Shasta, I am flying from Reno to SLC, then riding with others to Ouray.
My ideal plan for Shasta is to climb to base camp on Friday, summit Saturday, probably stay at camp Saturday night, and return to Bunny Flat early Sunday morning.
I just climbed Casaval Ridge earlier this month, though we opted out of the Catwalk; so I am considering Casaval again, or maybe Sargents/Green Butte.
