Everytime I see a list with dual Aggressors, the list is filled with a bunch of useless crap that could be trimmed off for more effective upgrades. Hot shot is nice, but you could use those extra 3 points to upgrade your mangler cannon to the hlc, which is better if you have the points.
The best build is probably:
igB & igD
Title
Predator
Advanced sensors
HLC
With two points to spare for initiative or autothrusters on one of them or inertial dampeners. Perhaps you could go FCS and get autothrusters on both.
All other builds are trash, and mangler is nice but over rated. Always go hlc if you have the points.
