MRM80 poptart Yes, when poptarting you will have to trigger ghostheat and nope, it's not bad at all. Some time ago I've discovered that 2xMRM40 ghost is actually very manageable: I can't recall the exact numbers (and I was using a Trebuchet 7M), but on a heat neutral map, the actual additional heat was around 3 to 6% of the 100% heat bar... Which is really low and negligeable, especially once you finish skilling the mech. Coring a linebacker with 3 alfastrikes while poptarting is priceless. If you are feeling to slow you can switch to a XL300 engine and +2 DHS by stripping some armor and removing 0.5 tons of ammo
