I've done this loop multiple times, some overnight trips, and one grueling 14hr single day hike. I would look into if you have one or the money for one, a bivy. Ditch the hexamid for this trip. There isn't much great stealth camping without crushing some delicate alpine nature and the tent platforms are first come first serve with some folks pitching 4 person tents.
You are going to get bugged. Bring a bug net, use it as a stuff sack. It's worth it. You'll be able to get a canister, or denatured alcohol.
And as everyone is saying, don't miss West Bond.
