Don't let the popularity of the "standard" traverse faze you! It's not done often, and I think its presence on guiding sites is more testament to the great esteem of the route with the guides than a large client base.
In preparation for my own trip, I made this Google Earth path if you want to check it out:
http://hexploits.com/files/High_Sierra_Ski_Traverse.kmz. Hit "Add Content" by Places and load up the path. Zoom in towards Mt Williamson. Enable the Panoramio photos and check out some of the scenery on the way. Basically, it starts on the Shepherd Pass trail head out of Independence, climbs to the pass, traverses Bighorn Basin, crosses the headwaters of the Kern, does some awesome stuff to cross the Kaweahs, traverses the cirques at the heads of Deadman and Cloud canyons, which are fantastic, then crosses the Tablelands to the Pear Lake Hut and Wolverton in Sequoia, near Lodgepole.
I'm interested in this route because, minus some variations, it's the highest and most remote you can get in the Sierra. The avalanche danger seems to increase as you go north towards Mammoth, but that may be due to more use and the visibility of avalanche runouts below timberline. The variety of scenery on this route is also higher: I've traversed (in summer) W to E along the Mono Pass route, and while it's beautiful, it's a little monotonous because a large part of the traverse is in a long E-W former glacial valley. The sides of the U are rather steep, so you will be exposed to avalanches from the valley flanks for about 10 mi through this part. One of the photos above corroborates this. Still, wherever you cross the Sierra, it will be friggin' awesome. Have fun!
