John, to answer a few of your other questions….
The "Snowpeak Starter Kit," is a pretty good deal, but it's a greater deal if you wait a couple more days, when REI comes off with their 20% members coupon. Keep in mind though, that the Trek pot comes with a steel lid, thats a bit heavy and overkill. Most people find the SP 600 to be the ideal size for solo use. Plus theres places where you can get custom lightweight lids for it. Also, looking back at my cook kit, had I known that I would be eating out of freezer bags as often as I do, I would have opted for the long handled ti spoons earlier.
About Jetboil's and heat exchanger stoves…there's an article here on BPL (its member access only though) that did a study on heat exchanger stoves like Jetboil, primus eta, etc. The findings summed up were that the extra weight carried due to the heat exchanger built into the pot, was more than any weight savings in fuel consumption…so all in all not really worth it. The only real benefits to a system like a Jetboil, are its user-friendliness
The Caldera Cone is pretty straight forward to use, once you've done it once or twice. Durability is kinda of an issue, unless you get the titanium version. The problem with the regular aluminum ones is storing it. The cones are are plenty durable, unless you abuse it. Most often, the cones are damaged when they are in someone's pack, getting smooshed. Therefore you have to be sure that you store the cone in a hard container of some sort. Sure you can buy a a 2 piece plastic cone caddy, but thats just an extra 2.8 ounces. However, i found that Half the caddy will nest perfectly with my SP600, so i can store the cone inside the half caddy/Ti cup, which saves me 1.2 ounces (when compared to using both sides of the caddy) Not sure if this applies to other pot sizes and their correspondent caddys. Also, they have a compact version of the cone, that fully stores into your Ti cup. They are slightly less efficient, but had I known the how slight the difference was, I would have gotten the compact over the regular cone, for my sp600. Durability isn't a problem here, because your Ti cup serves as the caddy. As far as the aluminum cone itself, well so long as you dont fall on your pack/kick it,etc ..i dont see any durability problems. Cool thing about the cones is that the aluminum ones have the option of running esbit/alcohol, and the Ti cones, can do all that, as well as burn wood!
How does the Cone perform in poor (windy, rainy) weather? It does great in windy weather, because the whole cone acts as a windscreen. Rainy weather? well you'll probably have a harder time with this, unless you cook in a vestibule, but thats always dodgy unless you're using an alcohol stove with a very small flame (which the caldera cone stove does not have)
Titanium is really crappy at conducting heat evenly. Whether the handles get hot, depends on your set up. If you use a cone, the handles partially get hit by the flame of the stove, so yes they get kinda hot…just use an extra sock to pick it up. However, when i don't use a cone, and I use something where the flame is more or less under the cup (like a canister stove, esbit. or just a smaller alcohol stove, i can pick up the cup by its handles without any problem. I've never desired a neoprene caddy with any of my cups. I do use a fabric cozy with my freezer bag meals, to trap the heat of the freshly boiled water better. Thats the benefit of having a cozy. Once your water hits boiling, you can stop your stove, and pour the water into your meal. Then put it all into the cozy…and itll hold the heat, losing only a few degrees, for a Loooooooong time. Makes meals that require simmering, very fuel conservative. You can also make a cheap reflectix cozy for your pot, and it cost you less than 10 bux ( you need reflectix material, and the reflective tape to hold it together). I bought the materials at Orchard Supply. Both the fabric cozy, and/or the reflectix cozy is lighter than the neoprene used on the Jetboil Cozy.
As far as fuel is concerned, esbit is probably the hardest to come by. Alcohol is easy to find even in a non-outdoor setting. You can burn anything from yellow HEET, found at any autoparts store/walmart/ 7-11, to everclear grain alc, to actual denatured alcohol. You could even burn rubbing alc…its super sooty and has low heat, but it works. Canister's are easily found anywhere where they sell campgoods. In my experience you can run any brand of canister with any brand of stove (outside of pure propane). So i've ran snowpeak with my jetboil, jetboil fuel with my optimus, etc
