List looks very similar to mine- I go in 23. I started a thread in the Sheep forum on things not to bring on a guided hunt. After a lot of feedback and discussion I decided I am bringing my own stove, my own tripod and spotter. Easy way to save weight, but I like the idea of being able to do some glassing of my own. Ditto on having my own stove, want something hot while glassing, don't have to bug the outfitter, etc.
I had a really good option with synthetic insulation a couple of years ago with Nunatak- Apex insulation, completely customizable in regards to fabric, cut, length etc. Sadly it doesn't look like he's doing that anymore. Anyways will be bringing one of his insulated jackets and pants w/ me.
The Hille is a solid shelter, but if you really wanted to shave some weight I've used the Tarptent Stratospire Li enough now that is what I'm bringing- 2 lbs all in. If I already owned the Hille, I'd just take it though
Do you have a plan for an unexpected overnight bivy/Siwash? I finally decided I'd bring a lighter down bag (30 degree) and supplement it with a 50 degree syn (Apex) quilt. The quilt would go with me daily and the down bag remaining at camp. With an insulated jacket and pants and the light (12 oz) Apex quilt, I should be able to tough a night out on the side of the mountain. My "sitpad" is going to be a little longer than usual as well just for this scenario.
I'm also bringing my own food. If they have some things that look irresistible, I'll throw them in my pack- but I have my food very dialed in now and not going to change it.
Best of luck man!
