After reading some other forums and lots of tweaking, this is (mostly) what i currently use for this 'Mech. The build has two (2) free slots left, so adding some range by replacing one or both LPL with PPC is an option for maps like Alpine Peaks or if you're really good at sniping. Heat is very manageable with the LPL but can be a bit problematic with dual ERPPC (1.25 heat efficiency) but this is a heavy (not fat!) harasser first and foremost, so you can easily find time to drop the heat to safe/acceptable levels. Or for giggles drop a bit of armor and the AMS (and its ammo!) to equip BAP and TAG. 80 ton assault scout! YEAH BABY! I got some feedback about the fact that this build is kinda worthless and before i get more messages along the line of OMGUSUX: this build is mostly "just for fun". If you want to do some actual damage ... you should consider a different build (just posted a different one a few minutes ago which might help you do some actual damage).
while a fun build, I really hoped this build would do more damage. I would drop the engine for more missiles and a head laser to boot.
