I'm using a 2 LL + 4 ML cookie cutter loadout ATM and the heat isn't as problematic as I expected it to be. In fact, once I get it to 4/4 elite, I'm considering replacing the LL with ERLL (I can probably afford the extra heat). Overall I'd say it's a solid and viable robot, and I'd recommend it for anyone who likes agile, maneuverable mechs (especially medium fans).
So far, the main issue is that I sometimes only get to fire my left or right half of the body's weapons, which causes the other side's beams to hit dirt and waste heat...but I can just solve that by creating more weapon groups (i.e. group 3 for left side, group 4 for right side). Its heat management can sometimes be annoying but not as much as you'd think (especially if played as fire support rather than brawler).
