BTW, I do not recommend the route we took down the back side of Tyndall - it was a long slog over a lot of unstable talus with some picking our way through to find an easy way down the cliff bands.
Yeah, I noticed that loop down from Tyndall and around the southwest peak of Tyndall and wondered why you'd do that.
Figured you were a sucker for punishment like I am.
I wasn't planning on going down that way from Tyndall (wouldn't want to take my full pack up). I was planning on going up Tyndall from the north, doing down the same way. Get my gear and circle around to the west before heading to Russell. Kind of the reverse route you did in that loop.
If I did the Williamson > Trojan > Bernard > Russell route, that would mean going up Tyndall first and carrying my full pack to the bowl (possibly camping in there somewhere), doing Williamson (without my full pack, of course), and then across the peaks towards Russell.
The satellite views of your planned route doesn't look too bad (although I've been fooled several times by satellite views, so I always try to check multiple sources and trip reports before setting out off trail). It actually looks shorter and may be more scenic than going down through the Wright Lakes area.
Of course, I always have the option of going all the way west to the JMT and heading to Whitney that way if conditions prevent the overland route (skipping Russell, unfortunately).
When are you planning on heading out? Depending on the timing the Wright Lakes / Wallace Creek area should be fine, albeit a bit soggy in spots. I remember reading earlier in July that Wallace at the JMT was flowing pretty high, but that's older info. You'd be further up the basin and crossing the feeder streams before they all join together.
My first possible start date is Aug 13th, but I've been more inclined to go on my second choice on August 27th. Weather has been looking pretty bad this week, so will depend on how the weather looks next week and any trail reports I can get.
