That build is not entirely my idea.I got the idea from a king crab with similar build i met in the field of battle,, as enemy, a few times.He was devastating..I tried to copy his build and the results were great. You got AC 20 to open armor with the help of SRM 6 +A. The LB10X is for the open armor.The small lasers add to the firepower.
Endo instead of Ferro will save you 3 tons and let you run another heat sink on the engine and different energy weapons or a Command Console
Yeah, generally speaking you should aim more for Endo then ferro, but it's a great concept. The ac20 and the srm with Artemis sound absolutely devastating on their own, but the lb10 is a great idea. As for the extra weight, you do lack some heatsinks and possibly some speed. I am curious as to if it runs really hot, because it looks that way, and do the AC's sync up with each other? Either way, running this build more or less the same, I had terrific results. Six kills, and a ridiculous amount of damage. No screen cap sadly... I was running it with Endo, drop the srm 6 to srm 4, add ams, some heat sinks. It's amazing.
