"is the trade off between tall pots and wide pots basically packability and using as a mug more easily vs. efficiency or are there other factors I'm not thinking of?"
For me it is (right now anyway)
I know I could put a lighter cup than the Ti double wall but I have never had one and want to try it out. got a great deal on it here.
I have a number of set ups. I have a GSI Kettle, SP1400, Caldera Keg Set/Heineken model,
a GSI Dualist, and this one that I am going to try for a while because I want something small. I have a bunch of different alc stoves and canister stoves and have mostly use a white box from when they fist came out. I like the 12-10 a lot.
Your set up sounds good… it's got me thinking.
UPDATE: The folks at Trail Designs noticed that I have an aluminum ULC and offered me a deal to upgrade to a Ti (SWEET!) I am going to get the inferno for it.
Thanks Rand your awesome!
