Based on my games here's what I use to determine what HW's to field -
anti - AV10...AC, LC
anti - AV11...LC, AC
anti - AV12...LC, AC
anti - AV13...LC, ML
anti - AV14...LC, ML
anti - GEQ...HB, AC
anti - MEQ...ML, HB, LC
anti - TDA...LC, HB, AC
best, second best, third best
Bear in mind that it depends on what unit I take as to how efficient it is -
Hydra has multiple barrels, as does a HWS, so that makes them better than single weapons.
A Lascannon works well in a CCS because BS4 makes single shot weapons more likely to hit....not so much on a BS3 PCS like you have, so AC fits better.
The rest seems ok although I don't rate GL's and Sniper Rifles myself. Plasma Pistol fits better with Vets with Plasma Guns, but it's not a huge deal.
