Like a D-DC, but with more SRM and less ECM. The medium lasers are really holdout weapons, better to use your ammo first and then pull them out, or use them if you lose a torso. I personally put the SRMs on two groups, but they can be shot together for a 1.7 heat penalty. The alpha on this build is devastating - 70.4 damage, 80.4 with the lasers. If you prefer a cooler build, you could drop to SRM4's, and gain some accuracy for losing some damage, or drop the engine size, but I do not recommend that option at all. The Atlas is kind of garbage at stock speeds.
