Peter, I heard that future Arc AAA's will have heads a little wider than the body, to reduce resemblance to the Gaglite 1AAA model. Yuck. Here's another suggestion: just mill some flats on the side of the head. I'm thinking of two parallel flats connected by circular "arcs", or possibly just one flat, with the ends connected by one big "arc". I think that would look pretty cool, be easily distinguishable from Gag, and would fit in nicely with Arc's own trademark. It would make the "reflector" slightly smaller, but IMO that doesn't matter at all, since the reflector does practically nothing already. The flat part of the head would be a good place to engrave a logo, too.
