Hobbes,
thank you for the suggestion. You're suggestion gave me an idea, if I can secure an entry to Whitney, I thought about trail crest to UCL via Discovery and then out through guitar lake.

day 1 Trail camp
day 2 UCL via discovery ( option to summit whitney here or day 4 )
day 3 guitar lake
day 4 out

if this doesn't work out, I'd shuttle and do cottonwood pass route.
