Schwert,
Thanks. I prefer flask-shaped bottles like that for EDC. They are much less obtrusive than round ones. Of course, I have three Lexan flasks coming thanks to the 50% coupon code post here last week.

I guess I'l have to wait until gift-season before getting the Sigg.
Sidenote: do you know if the Sigg flask bothers airline security personal even if empty? I'd hate to get it just to lose it that way.
