Do we know where the Corsair's hardpoints are yet?
On my Mandalay, for example, I run a pair of C2 MCs and a pair of C2 beams and then I have turreted frags in the C1 slots, just to take potshots at anything as it flies past me, or as I'm turning to gain position.
Similar thing with my Python 2; C3 MCs, C2 beams and a C3 turreted frag in the dorsal hardpoint for the same reason.
This works pretty well and a lot of the time things go boom before I've even finished turning to get a target in my crosshairs.
If the Corsair's hardpoints are, basically, a pair of C3s, a pair of C2s and then another C2/C3 in dorsal/ventral positions then I'll probably go with a pair of beams and MCs and then a turreted frag on top and either a PA or Rail underneath.
