No ghost heat version to maximize number of ATM in on salvo with support weapons. Decent range and damage for 6x MPL without breaking the bank on heat. Faster alternative with cooler secondary weapons and extra room for tag/lap or more ammo. 4xSPL is heat neutral-ish depending on skills and should be used in sustained encounters at short range. 6xSPL isn't bad for low heat close defense. Adjust the extra weight to Tag, AP, armor or more ammo as you see fit.
