3x LLas, good fore both chainfire and alpha. AC2 for your right arm shooting, something really nice to use on other big and slow guys, and SRM for short range. Not too jumpy though, and you may have to watch the heat still. But really, if you see something banged up, just send that LLas alpha to the core.
Ha! I just came here to post this mech as I started running it tonight. I've been scooped! This is the most effective build I have run so far. Full stars! One tweak - I have one less ton of ac2 ammo and one more DHS. Only a handful of matches so far, but it has been enough ammo. I am also tempted to downgrade one srm4 to a srm2 just to fit in a third JJ and fill out all the slots...
Good build, I run something very similar but with Streaks and a AC5. The AC2 is nice to reach put and get that kill assist with.
