Early Season 2010 40 to 50 miler in Sierras

I am looking to plan a hike for a mixed crew of Scouts aged 12.5 and above with some previous backpacking experience. On the agenda should include fishing, peak bagging (class 1 or 2) and perhaps a mid trek food re-supply. Since I am off to Asia in August, I need to do this trip early, perhaps starting the last Thursday in June to avoid the permit lotteries.
Options I am investigating:
– Southern Sierras: Horseshoe Meadow to Mount Whitney via Cottonwood Pass/Rock Creek. 60 miles in and out from the trailhead. Ascent of Whitney via the Mt Whitney Trail could be optional.
– Mono Divide High Country: Vermillion Valley/ Lake Thomas Edison to Tully Hole as a loop trip, back to Vermillion cross country over Red and White Mountain.
– Cherry Lake to Sonora Pass/Pacific Crest in Emigrant Wilderness as a shuttle trip. Exit at Sonora Pass to Highway 108.

Thoughts, comments, other ideas welcomed.
