I'd skip the Artemis on the SRM4s as their spread is tight enough without it. Additionally you might want to switch the MPL for an ERML as it works pretty nicely in conjunction with your LPL. For pure close range engagements I'd prefer an ERSL or SPL. Finally, use the biggest engine available so you're able to keep up with the main force of your's. Always try to use Gauss ammo for crit padding your Gauss Rifle. You might want to skip a ton of Gauss ammo for another DHS if you keep that ERML. Heat should be perfectly fine when going with either of the small lasers, though.
Finally got my hands on the -D thanks to the CBill release (I simply refuse to spend any money on those 'reinforcements'...) and this is the first build I went with. Works like a charm.
