Like many I have made several (a few dozens...) alcohol stoves. They all work.
However I use the TiTri Caldera Cone system.
That is because it works exactly the way I like it. Best compromise between fuel efficiency and speed (for me...)
I only boil water, so the 550ml version works for me. I use the caddy as a mug and my re-hydrating container.
The cone works well in the wind.
No, I don't have to measure how much I use. I made a "snuffer " for the 10-20 stove. That allows me to put the flame out as soon as the water boils or is hot enough for my coffee. Then I transfer the remaining fuel to the snuffer and from that back into the container.
The snuffer at the moment is still a piece of doubled up aluminium foil shaped over the stove and cut to size.
