For using Handwavium, perhaps a general Handwavium skill, with specializations for those who concentrate on a particular type?
I'm also trying to think how to design advantages/disads for handling handwavium. The Jason's technomancy, the Wiccans on Grover's Corners, the Professor's Weird Science - each of these is a specialized way of handling the stuff, which would give at least a plus or two towards the handwavium skill? Perhaps it would be a general advantage with levels (Handwavium Focus, 2 points, 5 points per level?), with the specifics outlined by the player? I'm still trying to familiarize myself with 4th edition - I'm much more used to 3rd - so any help/comments would be appreciated.
