Maybe having this one between an SRed and an LRed would work best. This way it is balanced between an anti-cap ship role and an anti-fighter role (basically what the Moloch should have been, but wasn't).
An MRed or something. There is a large jump in the beam weapon damages. From GreenBeam to SGreen to BFGreen? And SRed to LRed? Beams either suck horribly or do too well.
The Terran progression is more like SGreen, LTerSlash, Green Beam, Terslash, BGreen
Terslashes are supposed to be an imbetween, but in reality they suck almost as bad as the SGreen, an MGreen would be easy, just turn the TerSlash into a LOS beam. I'm sure you knew all of this already, but... it just came out.
BTW, are you still working on that psycho Barney campaign? 
It's on hold right now.
