I'm using a lot of SPLas on my builds, but they are working, so screw it Can easily change to mediums for more range, but they are hotter. Do not use the lasers and PPCs at the same time, or you'll be a cooked bug.
I had a similar idea. Sniper with a knife-fight back-up. I do however prefer my PPCs in the same torso to avoid convergence misses.
