Eh then stick with those weapons. Piloting, consoles, stacking boff abilities, etc., all do a lot more for DPS numbers than weapons mods. So push the number up with the weapons you have and then, down the line, worry about the weapons themselves.
Yeah, extra acc goes to crtd and crth but one full acc mod becomes 1/4 of crth and crtd, so you lose like half a mod there. Acc overflow works on the main target with FAW, so 1/2 of your shots will benefit from it when FAW is up and all of your shots when FAW isn't up. This is because the extra shots from FAW bypass the accuracy mechanic because they always hit.
