Most wubs you can put on an Inner Sphere heavy so far. Mostly in the torsos and with a large standard engine. Plays exactly like the 5SS except more alpha, less range, and a good amount hotter. Thing is hilarious though running into mechs with a 54 point alpha in 0.6 seconds. The thing cannot alpha twice in a row on most maps unless you reduce the engine for a couple more heat sinks. Come-back from 2v6 on Terra Therma. Top Ace Moar cooling (probably a more viable trade-off)
5/5, Requires some discipline with heat management but otherwise pretty deadly if you line up the shot just right. I had to drop to the STD 280 version though as the 300 was just too much heat.
I like the build idea, especially since it can be copied to a deadly c-bill version in the 5SS STD version XL version w/BAP While I am at it, the weaker version of this build can be used on the 9S for leveling if you don't like ERPPC's
