can also swap the Torso Medium for another heat sink if you prefer. skill tree a5f5f9fcf76ddde560f0000000000000000000000e86f777fa5e7ac21200c
4/5, The downside here is that ghost heat exists Over my theorycrafting I removed the 5th laser as you suggested as an alternative, but came to the conclusion that you might be able to fit a cSRM6 in there, like a 'rocket launcher' that can be reused. If you get in HML range it should be possible to occasionally get really close back shots, where the spread of cSRM6 is not as noticeable. It's most important that the weapons supporting the HML don't increase the heat even further! Overall I think it's a good build though, splitting only takes a little bit more effort and 0.5s extra burn time.
Here's a nonsensical application of 'all the laservom meta' without tonnage left for heatsinks that I thought of, inspired by your build.
5/5, 5xHML + ECM is how I set up my Rainbow Crow. Not great, but fun. The ghost heat is real and hurts your DPS, but when cold you do have an alpha option.
