The mech that everyone forgot about. Standard lasers get -10% Duration, +20% Range and -10% Heat. Evidently, that can be put to good use. Ideally, you'll just alpha all 3 lasers for some remarkably powerful 27-pinpoint alpha right where you aim! A little too cool? Go faster, or equip some ML in the other arm. A standard engine can also be considered, though you'll be really slow! Just make sure you protect that right arm from harm!
