My favourite "trick", on all my big ships, is to fit a couple of overcharged frag' turrets, with the Drag Munitions XFX, to spank anything I can't keep in front of me.
Works ridiculously well, IMO.
Problem with relying on turrets is that if an attacker uses chaff they'll keep on firing and missing.
If you have laser turrets, that's going to drain the PD and MC turrets will use up their ammo.
I'd mitigate that by using Efficient lasers, which can (basically) fire forever without overheating or draining the PD and I'd use frag' turrets 'cos they only fire at close range and so they're still likely to hit
something even if your attacker is using chaff.
Added to which, using the Drag Munitions XFX means the attacker is kind of stuck there, taking more fire from the frag's.
Only other thing to be aware of is that when turrets
miss, when an attacker uses chaff, you can end-up hitting other ships and turning them hostile.
Either be ready to stow your weapons or have a no-turret fire-group you can select to disable all your turrets temporarily.
I can see the PC causing people to come up with a bunch of new turret-related tactics.
