I was always a fan of the Extreme Rage/Empire/JT Overdrive due to the lack of paddles that extended up into the body. The rotating ring around the feedneck was nice and unobtrusive, combined with a little board, motor and single 9v and that's a pretty compact package. I've been meaning to get a body designed up to have printed that uses those internals like what Simon did with his Pico and the Halos.
