Whatever your list, force them to turn.
The best defender pilots still cap at 8 PS in general, well flown aces can arc dodge them, just don't let yourself be caught in their K-turn web.
Rebel swarm or Rebel regen can weather the storm and turn the heat back on the defenders.
Place asteroids to block straight flight paths (So if you want to fly a ship across the middle of the table it will need to turn at least once to avoid an asteroid), keep the flight blocking asteroids roughly 3 move range appart from the others (basically try to make a W shaped asteroid formation).
