You might want to look at the Bass Pro Shop White River Classic Ultralight. I don't know if it is small as you want (it's 2 1/2 inches and 2.2 oz.), but I bought one last year for a 6' 2-weight and it works fine. It's not powerful by any stretch, but I don't suppose you need or want one for a 0 or 1 weight anyway.
