The premiere pilot for the K-Wing sits at 29 points. You can be assured however it will take up a large portion of your squad though if you choose to tool her up.
The pilot ability is amazing allowing you to regenerate a shield by removing an attack dice, this isn't a bad choice when paired with the Twin Laser Turret. However, on the flip side of course, you can opt to remove a shield and increase your attack dice by one, this could mean a 5 dice Homing Missile or a range 1 4-dice attack with the primary weapon.
Generally speaking, you'll want to either gear up Miranda with a Twin Laser Turret, and then either decide on the bombing path (Sabine, Extra Munitions, and bombs of your choice) or the missile boat (Extra Munitions, Homing Missiles) which is great for an 'Alpha' strike as well as cleaning up enemy aces late game.
