Don't joust with a TIE swarm. Fly in circles around a tight asteroid field so that he has to break up his formation to chase you. Turrets are tricky because you need to get out of the mindset of "I need to get closer, from the side or rear, to the enemy" that dominates most small ship movement.
I'll keep this in mind. The one thing that makes me hesitate about a big ship list is the low number of attack dice. I know the big boys are tougher and can last longer, but I like rolling 10 attack dice per turn if I can, especially against those delicate ties.
