Some Dakka in one hand, and dual Beams in another. Less armor, more heat, but more fun. Oh and careful with your ammo running out often.
I ran this on the 1N when I was levelling it, I think I just ran a 300XL and slightly less heat sinks. It's a good build in the fire support role. The large lasers give you a reasonable amount of firepower if the AC2s go dry, and you've got good left and right side options for poking round corners (as opposed to say, the trip AC2 build, where I'm always trying to go round the right hand side of cover, which isn't always practical).
I was doing the 3x AC2 build, In fact that was the reason I buy this mech way back. But I learn that a LLas or two goes a long way.
