If you possibly can, start TABA with x2 scoring running.
When trying to light the Elf Rings to start TABA it is best if the Legolas ramp is lit for an Elf Ring as you can combo it with the Aragon ramp or Gimli saucer to get TABA ready to start once the ball returns to the right flipper. Don't forget that you can extend TABA an extra 20 seconds by collecting a Palantir award.
