ski from Fallen Leaf lake to Lake Aloha, Deso wilderness

I posted about this to rec.backcountry, but could not get a response.

I would like to try backcountry skiing for the first time. The idea is
to ski from Fallen Leaf Lake, Tahoe, to Lake Aloha, Desolation
wilderness. It's going to be my buddy and myself (he has good
experience in bcs, my experiences are in XC racing and backpacking in
summer). Does anyone have a suggestion on the best starting point? My
Tahoe Ski touring book suggests starting at "Tahoe Mountain Road" in
South lake Tahoe, but the book is relatively old (judging from 80s
style clothing and 75 mm bindings they use ). Does anyone have
comments (snowmobiles, private land crossings, etc)? The plan is to
ski up to Aloha on day 1, sleep, and ski down the next day.

Also, looks like the backpack will be much heavier compared to summer
b/c of all the winiter clothing. Does the fact that you are skiing
instead of walking (i.e. less pounding on legs) make the pack feel...
well... lighter?
