I usually go for the ISD on the left first, firing one torp at each shield gen and then finish them off with lasers. If I'm about to die, I go ahead and just use all of my torps on it and then try to fly around to the bottom. If I'm not dead yet I peck at it with lasers until I either get vaped or suicide into it. Once it's dead I pop a torpedo into the bridge. I then use roughly the same procedure with the other ISD, minus the dying part.
I forgot how to make witty sigs.
