Original Super-Cool Standard Engine This is and optimized build for the LL heatscale. The speed is great, and being able to fire 3 LL you trade damage with exposure time (considering the speed too other then having to fire only 1 group, it's a big difference). If you prefer you can put 2 LL in the arms, I think this grouping is better and the ST hardpoints are not that bad anyway. The big advantage is the 42 alpha in brawl range, on an fast heavy with JJs.
5/5, I really like the 340xl engine version of this. I'm using it in my CW drop deck currently and seldom have a bad game running it. I moved a Large Laser out to the arm, other than that I'm running an identical build.
