This monster can dish it out at all ranges. 2 PPCs for long to medium range engagements (over 65% cooling efficiency when fired alone) 6 ML for close encounters (over 55% cooling efficiency when fired alone) 20 DHS works great for heat outside of the 90M - ~400M hot zone when all weapons can be fired at the same time. Be careful in at those ranges to not push yourself towards overheat. Carefully fitted 360STD engine with 4 internal heatsinks will keep you above 60, and you'll be moving fast once you have speed tweak. The AMS is less optional now days than before, but if you really want you can drop it to fit one more DHS into place.
I am hoping to try this out with ER PPCs once I have finished elite, but I have a feeling it will still be way too hot, even if only fired at long range.
my version: 2 more heatsinks, little less armor and little less speed, but the 2 DHS are worth it imho if you only use PPC it takes 13 linked shots to overheat (forest colony, no elite skills) without full basics:
