Very similar to what I was thinking. Only differences I had: - Max the armor on the legs by stripping it off the missile arm. - Shift the heat sinks all to the same torso as the three MPLas for crit padding, including one out of the engine. (There is no reduction in heat efficiency.) - Move all ammo to the protected side. One ton in the head, one in the CT, one in the leg, and one in the arm with the AC/5 as you have. Otherwise, I think this looks solid, and is likely what I'll try running.
This is how I would build it: Or if you'd rather keep the armour: In either case going std325 + ferro has no downsides that I can see, it's the exact same build only a little faster and with more ammo or AMS.
