Loving this build. Averaging 500-600 damage per round, never less than 350. I ran a similar build on my Atlas D-DC for a very long time, but the extra mobility here and lower profile increases survivability much more than you'd expect with an XL engine.
Doesn't the 9S have 10-5-2 tubes only, making the 3x6 kinda obsolete? I'm running the exact same build but with SRM6+4+2 and Artemis.
