Here's the ship:

Maarek Stele - TIE/x1 - Advanced Targeting Computer - Calculation - Advanced Homing Missiles - ________

So, which Modification upgrade do you think best fills in the blank for this ship?

Twin Ion MK II if on a budget, Engine Upgrade if you wanna spend 4...

Between needing a focus token for calculation, but needing the TL to use cluster missiles, then *another* TL to use ATC, it seems counterintuitive, so Engine Upgrade would be tough, since you'll need those actions to reacquire TLs and get focus tokens

Or you could always take nothing

Stealth Device.

You've poured so much offense into that bugger, you want to add some survivability.

Engine upgrade to help with arc dodging, though this is better with Vader.

Looks like I'll be trading in the Cluster Missiles for Advanced Homing Missiles. Does this change anyone pick for best Modification?
