After not having enough speed, I went to find a 300 engine mech. This is good, frankly! I didn't pick up the Ferro, though, since I'm still fitting out Mechs with DHS... It runs a bit hot, so having a group to chainfire the pulses is probably a smart idea. Though this will likely get better when I finally master this mech. An alternative might be to drop the MGuns for another heatsink, but I get the feeling that Ferro might make it impossible. 4/5 for me. Has what I want in it!
My version : less max dps and a little less armor for a way cooler build. You still can sacrifice range by using a LL instead of the erLL and get a 40% heat efficiency, but it might not be worth it.
Artemis isn't as necessary imo, but 2 SRM6s burn through 2 tons of ammo in 16,5 salvo's which seems a bit shabby. I swapped Artemis for yet another DHS and 1 ton more SRM ammo, giving me 25 shots. Oh and a sick sustained DPS of almost 7.
I wanted AMS and a cool build with Artemis so I ended up using one of the stock Shadowhawk engines. Gives the 1 DHS slot, good compromise in speed and a nice dps with enough ammo and armor.
Instead of SRM6+A I downgraded to SRM4s which have innately low spread. Added in a lot of DHS, had 20 in an alternate build with all pulses and an XL engine but I prefer this.
