Compact Heat Sinks are an IS tech (experimental in 3058), they take up 1 slot, dissipate like a double hs, but weigh 1.5 tons.
Basically, based on ingame stats:
Slots: 1
Dissipation: 0.22 (same as DHS)
tons: 1.5
The problem is basically, many IS 90-100 ton assaults can't bring a hotter weapons payload because you run out of slots to put in DHS before you run out of tonnage. If we add CHS to the game, IS assaults will have a better build option than cramming dual heavy gauss into everything.
