It deals damage way better than my original plan. Always, always, always try heavy lasers. You need to get closer to use the missiles anyway. Missile ammo is a touch short, but weapon skills should help alleviate that.
Might want to drop one or both of the DHS to get an extra ton or two of ammo. Two tons of ammo seems rather low for a pair of 6s, especially where overall damage potential is concerned. I do like the mix of HMLs with SRMs though; that range convergence is spot-on, and the alpha is very nice for just 4 weapons.
