I'm from the opposite coast so my reply isn't tailored to your specific route. Based on the gear list in the first reply, though, here are some thoughts based on similar trips in AK and the west. The original respondent knows more than I about your area, so I guess defer to him.
>g14's with the walking spring
Overkill below WI4. The steel Air Techs will climb vertical ice and are much nicer to walk in. G12s are somewhat heavier with better climbing and poorer walking. The front points break off the aluminum Air Techs if used on too much steep ice. Yes on the walking spring.
>lightweight trango mountaineering axe.
Long one for v thread?
I have found Neutrinos and other little ones perfectly OK with huge gloves
>8.1mm beal randonee rope
> lasport trango extreme leather boots
I haven't worn them. My Nepal Evos are OK to around -10F, maybe. I would put my money in some of the new synthetic double boots if it's really going to be subzero and you are going on to colder and longer things. If you have plastic boots, get intuition liners.
>extra socks, 1 pair
>cannister stove w/ heat exchanger gear
MSR Reactor + shovel + parka = stove, tent, and sleeping bag. I have not had good experience with Jetboils on multiple winter outings. Maybe they just needed more finesse. Reactor rules.
>.75 liter thermos
No. Wrap nalgene in clothes.
> 3liter platypus
Do you need to carry so much liquid if you have a stove?
> 1 liter nalgene widemouth
> silkweight top w/ arms cut off
Yes. Helps keep arms loose.
> mid weight top
> union suit
>mid weight bottoms
Are these either-or? It seems like a lot of binding layers. I would just wear a powerstretch or powerdry unionsuit over the tshirt. Invest that weight in a warmer parka and boots.
> hardshell bibs
I would opt for lightweight shell pants stored in your pack, and wear warm softshell pants, which I think are easier to move in and more comfortable. On a trip I once brought nice shell pants and was continually zipping and unzipping them to vent (when I couldn't stop to adjust layers); now I just wear softshell pants and sweat if I need to. They dry fast in the cold. If your upper layers are long enough, you shouldn't need bibs. Sew a skirt of fabric on the hem of your expensive shell jacket, if needed.
> softshell jacket
no, unless you expect abrasive rock climbing.
lightweight hooded windshell
> fleece jacket, 300weight polartec equivalent
Thin down or puffy jacket.
Yes. Wild Things belay parka is awesome— nice and long.
Yes. Huge ones. With removable puffy liners to fit over your gloves. My hands are too big to do this, unfortunately.
>pack without lid, frame and extra straps: no more than 2.5 pounds.
I like the Granite Gear Virga, at about a pound, for this sort of thing. The collar goes up to your waist for emergencies.
> ascent skis.
> hiking poles
yes. Whippet? I don't know the route...
> 1 goo every 30 minutes
If you have a dehydrator, you can make fruit rollups out of apple sauce. These produce less garbage. You can also buy maltodextrine and mix it with protein powder, salt, vitamins, and flavor, to make your own Gu. Keep adding the DIY powder to your Nalgene. I like Gus but I hate the sticky trash.
> 2 ramen for lunch
I don't think Ramen are worth the space and trash, though I guess legendary feats have been accomplished on Ramen... How about oatmeal packets, which can be consumed with cold water and powdered milk.
+ sausage or jerky. Protein, protein...
> 2 clif bars for lunch/dinner
Yum. You can make your own.
>1 freezedried soup for dinner
plus olive oil or cheese or nuts
>+3 ramen, +5 goo emergency food
You could make some brownies with good stuff
>tea bags and sugar
I'd skip this and just bring powdered drink mix in a little container. It seems simpler.
> 3 chocolate bars with highest possible level of cacao and butter
Yes! They do horrible things to cocoa between when it's on the tree and in a candy bar. Buy some fancy ones that haven't had the butter taken out and then put back in. If you like nuts you could buy the cocoa beans and eat those.
>expedition weight top.
what is this? another shirt? If so, skip
>integral designs mk1xl tent
shovel and tarp, or BD Firstlight, etc. I don't have a bothy bag, but I have wished for one while sitting out in the open melting snow or resting.
>40d down sleeping bag
+ etcs like a sparker/lighter, knife, blister stuff
