Andor is the only U-Wing pilot with an EPT available. With his pilot ability, it is best to gear him to support self-stressing squadrons.
Kanan Jarrus pairs well with Expert Handling, allowing the U-Wing some amazing manoeuvrability. With Experimental Interface in the modification slot, you've got a ship that can punch above it's weight class in terms of action economy, but also stress shedding ability.
Fire Control System is always a solid choice for any ship with 3 attack dice but you'll quickly realise the price tag starts to get out of control rapidly.
