Boltons

Booster
With most mechs, (Not Neo or Hog), you can carry two Longhorns at level one with these. Osprey and Chopper carry even more later in the game. Saucer has blink, making it powerful for a Saucer to use them. Bomber, Striker, and Hog have to land too much to benefit, and Neo seems to not gain a speed bonus from these.
