The Evernew tea kettle is a possibility, since it's wide and short. It's 0.8L so it's not a whole lot smaller than my Evernew 0.9L already though. I kinda like it though. I wish it was 0.7L instead (then maybe I could justify buying it!).
Maybe I just shouldn't worry about it, but I'm trying to not only lighten everything up in my kit, but also get as small as possible (just did a 3 day trip in a GoLite Ion, but with no cooking).
