Wow Luke that's a sweet setup. Looks like you had a Jetboil SOL before JetBoil built it. Is your Jetbiolette cup smaller than the SOL cup?
I used the MSR superfly for quite a few years. Good stove at the time. A little bulky. Last Spring I purchased the SnowPeak Litemax stove. It folds down flat and weighs 1.9 ounces. Good output and easily stored. Too early to comment on durability but I like it so far.
The past few years I have used the JetBoil PCS.........but being a "weight weenie", as Aron would say, this last year I decided to try the new JetBoil SOL TI. Swung by REI on the way to the hills and used it on a weekend scouting trip. I was really disappointed with the inconsistency of the auto ignitor actually igniting the flame, especially since my older PCS lights the first click - every time!. Thinking I bought a lemon, I returned it to REI and exchanged it for another SOL TI.....same issue! Although the ignitor can be annoying, I am willing to put up with it for smaller size and 6 ounce reduction in my pack.
Now for the disclaimer:
The follow tests were conducted by a person with absolutely ZERO scientific background and realizes that these test will more than likely be scrutinized heavily due to one or many factors that would render these tests of little to any actual real world meaning.
All tests were done at room temperature with 500 mL (the fill to line) room temperature water.
Room temperature fuel canisters boil times:
Jetboil with jetboil stove:
2 minutes 5 seconds.
Jetboilette with Soto stove:
1 minute 35 second.
Last night I put two full fuel canisters in my freezer that was set at -10F.
I quickly took the first out and screwed on the jetboil/jetboil setup and it boiled the 500 ML of water in 3:45 seconds.
After that I took the 2nd freezer canister and screwed it onto the SOTO stove and fired it up. It boiled the 500 mL of water in 1 minute and 50 seconds.
So the coldest canister did have some apparent affect on the SOTO's performance but not much from what I can tell. Where the jetboil/jetboil was nearly twice as long to get a boil and the flame was noticably smaller and quieter than the Soto with the cold fuel bottle where I couldn't notice or hear a difference between the room temp and the cold fuel bottle.
Overall I'm VERY happy with my findings so far as my new setup that is both 25% smaller and 25% lighter and boil times are twice as fast in colder climates. I think this could be one of the most fuel efficient canister stove combos out there right now.
