If you're in the mood to do a lot of pinpoint damage at respectable range (i.e. beyond SRM Hulk Smash distance) the Cataphract Hero, Ilya Muromets has a set of three medium ballistic hardpoints and tonnage to fill them with AC/5 and LB 10-X. Tier 1 AC/5s and Tier 3 LB 10-X has virtually the same rate of fire as well.
Just sayin'.
I've been having some real fun ravaging lights at the range where they tend to run straight in at you, popping annoying VTOLs/vees and generally making myself into a ballistic-heavy menace to society. It is reasonably fast, well-armored, carries plenty of ammo and backup lasers, with very good heat management. The downside is much of your firepower is in both arms, which makes shielding fairly ineffective, but as long as you're fast and accurate, with a decent sense for positioning, it isn't too big of a disadvantage.
