"Looks like over Cottonwood Pass/Siberian Trail/ Soldier Lakes/ Sky Blue Lake/ Crab Tree Pass/Upper Crab/ Discovery Pinnacle ect. Seems pretty straight forward and looks magnificent from photos."
Sounds to me like you've got the route dialed in. Yes, it is magnificent, and far from the madding crowd. ;-)
"Visits from bears are not on my list of favorite Sierra experiences. I have a BA UL Fly Creek2 so would be looking for suitable terrain for my four star hotel :)"
You should be able to find a suitable location somewhere between Upper and Middle Crabtree Lakes, and I doubt you'll have much problem with bears there. Down below Middle Crabtree Lake is another matter. Also, Miter Basin, including the area around Sky Blue Lake is definitely bear country. Your best bet for avoiding them if you decide to camp in the area is to bivy at either Erin or Primrose Lakes, up above the main basin. If you are not carrying a bear canister, though, I'd push on to Soldier Lakes at the headwaters of Rock Creek if you are going part way out on the second day. There is a bear box there and it's only another couple of miles of easy hiking. The other alternative is to hang out in the Crabtree Lakes area the rest of day 2 and go all the way out on day 3 or 4. However you choose to do it, have a great trip. You'll be going thru some prime real estate.
