the BAP is due to having .5 tons left over, dropped a HS and added the BAP which should also help you pick up targets. I will be working on some more builds using different engines - but for now these are some quick fix mods for people that want to get the highlander and can't afford a new engine.
I'm not so sure sniping is this variant's forte. Sniper builds using Gauss and ER PPCs have a nice balance of heat; this is a very hot mech. Although I do understand the power of a PPC boat.
Try this one out. Very very similar, but I've optimized it for managing heat. Put the two normal PPC's in a group, then the two ER PPC's in a group on chain fire. You'll see the top of the leader board a lot in the current meta.
I like the XL engine in this mech, as once your torso goes down with your 2 PPC's, You are useless any way, so good on that. 3-5 stars, since I think there are better builds for the chassis.
