I've just conducted a backyard test of my Clikstand. Caveat: conditions may not be what you normally encounter. It's about 75 degrees here, with very light breeze (<5 mph.) I put 3 cups of water in a .9L Evernew titanium pot, with the lid laid on (not firmly in place). I only used the Clikstand base, not the upper windscreen, hoping to simulate a stronger breeze. I filled the Trangia stove about half full. At 5 minutes, I had small bubbles clinging to the bottom; at 10 minutes, larger bubbles on the sides and bottom, at 11 minutes I had steam and a light boil, and at 12 minutes I had a full rolling boil. I still had about a third of the fuel left.
I think the Clikstand will do what you need it to do. It also has the capability of using the 1.3L Evernew Titanium pot. It's incredibly stable, and the base (which is also a ventilated windscreen) and upper windscreen have managed any wind I've encountered. (I didn't go look this up, but there's a review of the Clikstand on this website and I seem to recall that, to a point, wind actually improved its fuel efficiency - but you'll want to find the review and verify this yourself.)
Now, as to weight: The .9L pot and lid weighs just shy of 5 ounces. The Clikstand base, upper windscreen, and Trangia stove (with both lids) weighs 9 ounces. So, you pay a weight price to get the performance you need (you can get the same performance with a 3-ounce canister stove - but you need to include the 3 ounce empty cylinder weight, for a total of 6 ounces.)
If you're absolutely wanting to use an alcohol stove, and are willing to pay the slight weight penalty, the Clikstand will work. If you're interested in having one, I'd be willing to part with mine (plus both pots) in exchange for the shipping cost. Give me your email if you're interested, and I'll contact you outside the forum.
