Of the 75 pounds of gear that I took, there were a few pieces that proved indispensable. By this, I mean that without this gear, the trip very likely would have failed. Here is my top 10 list in no particular order:
Exped Downmat 7 UL -- Combined with a Z-rest, this mat kept me off the snow and very comfortable. Towards the end of the trip, ice got inside the mat, but it still functioned well.
Jetboil Helios with custom carbon stove board -- The word on the street for stoves was MSR's XGK. However, after experimenting with the Helios, I felt it made more sense. This was confirmed on Denali. The Helios is a system that has a built in heat exchanger and cozy on the pots. The pots fit firmly on the stove. The stove has an integrated wind screen. Although the stove requires propane/butane canisters, it allows for a liquid fuel feed, which allows the stove to work fine at higher altitudes and colder temperatures. Finally, the whole system was very efficient. For 1 large Jetboil fuel cannister, Aaron and I got 3-4 days worth of water and cooking.

Mountain Hardwear Trango 2 -- This tent protected us in gale force winds and withstood meters of snow. Inside it was roomy for two people and has lots of pockets for organization.
Julbo Trek Glasses -- I had no idea how bright glaciers were. Luckily, I had these.
La Sportiva RST Skis w/ Spitfire Boots w/ RT Binding -- The RST ski is a light mountaineering ski. Combined with the RT binding and Spitfire Boots, the setup was key to being efficient and fast going up and down. For true ski mountaineering, the Spitfire boot is really on of the only options out there. It has a full coverage sole. It keeps snow from entering the front of your boot. It has good ankle articulation (not the best, but good enough for hardcore mountaineering). It is pretty minimal with only two buckles--light, but has good support as well.

Camp X3 600 Pack -- These packs weigh about a pound, yet are able to hold all that is necessary for a summit bid. I've used this pack in nearly all of my other mountain projects. For most of the trip, it was relegated to a sled duffel, except for summit day.

Montbell Thermawrap -- I've had this piece for 3 years. It's been used a lot. It got used on Denali every day. It's probably the best puffy I've owned. It's got holes in it; it's discolored, yet it still functions well. Having been through so much with me, it's developed a high sentimental value.
Gore Active Shell (Arc Teryx Alpha FL top, Millet bottom) -- Active shell is a newer product from Gore. What makes it great is that it is much more breathable than other hard shell materials, yet it still is a hard shell. It keeps wind and weather out, but breathes well enough to allow a person to put out a reasonable aerobic effort without getting drenched. From base camp to the summit, I wore my Active Shell pants almost exclusively. Above, 14k my Active Shell top was a mainstay.

Snow 'Chutes -- Brian Harder supplied these. Their weight to utility/strength ratio is very very high. We used these things to anchor our tents. Dig a little hole, put a snowball in, then stomp, and voila, an anchor is set.
Gregory Whitney Pack -- This is a gear hauler. There were a couple days where I couldn't get this thing on my back without assistance. Once Aaron hoisted it onto my back, I was able to slog in relative comfort up the mountain.
