The idea behind this build is to make a zombie with a full shield side. Not my idea actually, I stole it from Sp4rtan (who also mount a SLas on the shield side, but I don't really see the point). You can of course tweak it for max engine (+1t), one more DHS or more ammo (though I don't think it's needed) by removing JJs or armor. I dropped a few times with it this afternoon, that was good, but to be honest I'm not sure about the impact of a STD engine on survivability, I'm mostly cored on CT first (and usually don't survive long after losing the LT). But it make a nice alternative to the classic 2 LPLas + 6 MGs build running an XL, cheaper and maybe safer, without major drawback (same speed, same amount of jets, similar dissipation).
