Arm mounted weapons, 100+ km/h, good heat efficiency, bonus range to both ERML and UAC. The only downside is the lack of JJs, but you can either downgrade the engine and downgrade from FF to light-FF, or simply downgrade to non-ultra AC and/or remove a ton of ammo and/or downgrade to light-FF. Spoiler: 2xJJ - AC10 version Spoiler: 1xJJ - UAC10 - some armor shaved Spoiler: LE250 - 1xJJ - UAC
