I thought I'd update regarding ongoing "trials" with this rig and how the set is working out. I've boiled about ten liters and several more small volumes with it, now and have revised my windscreen to allow more air draft from the bottom edge (and less weight).
The stove burns powerfully, and I am getting very good boil times in temperate weather. For example, this past weekend, I brought 900ml of "cool water" to boil in 1:45, with the windscreen in place and stove nearly on full high. Most of my boils have been slower, at lower burn rates, but still notably quick. It also simmers pretty well, as long as the windscreen is there. The titanium has lightly discolored, which looks cool anyway.
The pot is certainly part of the "fast boil" equation and I've been very happy with the handles, pouring ability and shrouding of the heat exchanger fins, but the Achilles heel to the pot remains that lid: it does not like the heat from boiling water below it and the hot air rising up the sides -- the tab on the side of the lid gets mushy and has further deformed. Now, this is a problem: the lid is designed with a nacelle in the center that fits a fuel canister and a flat lid replacement won't fit over the top for a "self contained" rig, as I want for the Scouts that will use this.
I have written to the manufacturer, seeking help and suggesting they take a look at the material used. This coming week, the stove swaps over to use/review by nearly 20 Scouts, so we'll see what their feedback is after using it.
