Mt Whitney Zone Forums General Discussion Mt Whitney (MR), Mt Muir & Mt Russell - looking for advice

I'm part of a group of four fairly experienced climbers (we have several fourteeners between us including Mt Williamson, Mt Langley, Mt Whitney Main Trail, White Mountain, and Middle Palisade). We are doing the Mountaineer's Route about 3 weeks from now and I'm looking for advice on gear, routes, etc... We are doing it as a multi day trip as follows: DAY ONE: Trail head to UBSL. DAY TWO: Summit Mt Whitney via the MR as well as summit Mt. Muir, then head back to UBSL. DAY THREE: Summit Mt Russell via the East Ridge, then back to UBSL. DAY FOUR: Pack out.

Appreciate any tips!
