I've been running this with a XL280 instead. When its good, its good. But I've been steadily declining in success with it. Trying out a standard AC/10 instead.
This is very similar to what i first wanted to do with this mech and had a great first round. I have a stock engine, but more ammo, the LBX is (like in the Centurion) an Autoshotty, so i highly recommend more ammo for it! I finished the round with CT and both ST orange or cherry... don't know how i lived, but i lived.
I run mine with an XL295, 4 tons of spammo, and 2 JJ. To me it feels like a Yen-Lo with better hitboxes. I have to get close anyway for best effect, and the better hitboxes help. I actually got the "Yep, Dead for Sure" achievement (finished match under 19%) running this thing. The hitboxes are just that good. Even moar wub, and better spammability on the LB10. My scores actually look a lot like my Yen-Lo scores in terms of kills and damage. I want to see how it does once I unlock the double-basics. So ruthless
I played around a little with this to put an LFE in, but I'm also not a big fan of LB10X. Here's what I made, mostly similar: Deviating strongly along the same lines, I replaced the MPL's with ML's and dropped a DHS to fit a UAC10 in there:
