I love the support vehicle rules. I can reproduce a wider range of modern day vehicles than with the combat vehicle rules. This solves my biggest problem with the combat vehicle rules: the VTOL problem. I can't model modern day VTOLs with the combat vehicle rules (they simply aren't fast enough), but by using the Support Vehicle rules, accounting by the kilogram (including with the 12 ton Mil Mi-24 Hind) and using individual launch tubes (from the Protomech rules but doubled weight for Inner Sphere tech), I can. Sure, I'm probably cheating by ignoring the (sometimes arbitrary) restrictions on construction, but I can do it. I'd marry these rules if I could.
