Dual LB20X on the HBK-IIC can't properly be called a troll build. It's a bit on the slow side for a medium 'Mech, but it is absolutely devastating. It's the only dual 20 config that doesn't trip ghost heat when you fire both guns at the same time, so you can snap-alpha over and over again without any heat issues.i I'd recommend dropping 0.5t of ammo so you can squeeze in a jump jet, but otherwise that's pretty similar to what I run on
mine. As long as you don't facetank and play more as a poptart-brawler and ambusher, it's a config that can punch
way above its weight class. No IS 'Mech below a heavy can pull off dual 20s of
any type as a serious build, but the dual LB20X HBK-IIC is a cold-blooded murderer.
The LB20X can also be swapped out for a pair of
Gauss with no other modifications, allowing you to turn your ambush brawler into a sniper at the drop of a hat.
Forget the one with the MGs, though. 2xMG is
not worth losing half your main weapon throw weight. If you want to make use of the energy points, drop to dual UAC10 and take some MLs or MPLs, or else go quad UAC2/triple UAC5.
