I also use only B class, also mass is not an issue if you have +50 % FSD upgrade
Also, I do not use heat sinks, I use AFM unit to repair heat damage![]()
How does that work out in the "heat" of combat (no pun intended). I tried this a while back - AFM for Vulture canopy and I could never keep up.
Given how hot and how much damage is taken with a full on meltdown 180% + your modules would be glitching so badly I suspect you'd lose the fight before you got a chance to find somewhere quiet to operate your AFM. I say somewhere "quiet" because in a lot of builds the AFM might have to be inactive due to power plant restrictions and therefore need rebooting???
Perhaps some build details would help
