I went for a slower light mech that packs a heck of a sting. It's a somewhat different philosophy from most other 3025 lights, but it seems to fit the concept.

I included some standard canon-mech bad ideas in there - in particular, the HS allocation was designed to balance the mass of the unit for a smoother jump (and to ensure the laser was totally lacking crit-padding).
