So: Experimental Interface:

Once per round, after you perform an action, you may perform 1 free action from an equipped Upgrade card with the "Action:" header. Then receive 1 stress token.

Who do we know that loves stress? Shaft! Soontir Fel.

How's this look:

Soontir Fel — TIE Interceptor 27

Expert Handling 2

Targeting Computer 2

Experimental Interface 3

Royal Guard TIE 0

Total: 34 points.

Fel can Boost or Barrel Roll every turn, and Target Lock + focus every turn. Expert handling even gives him a tiny bit of extra survivability.

What else goes well with Fel and Experimental Interface?

Man, I would just leave PTL on him and not worry about experimental interface. If it aint broke

I'm not sure EI and Expert Handling is a good idea. What if I don't want to barrel roll? Then I'm stuck taking only 1 action.

...and Target Lock + focus every turn.

No, he can't. Not with Experimental Interface, anyway. Targeting Computer adds the Target Lock action to your action bar; the upgrade itself does not contain an action that you can trigger with Interface.

Experimental Interface is cute, but at the end of the day none of the upgrades you can combine it with do better than PtL. In fact, you lose a lot more options than you gain (EDIT) on Soontir, I should probably clarify.

Fel + PtL go together like PB&J.

Tycho PTL Daredevil Interface?

You could also do Squad Leader, but that would mean flying in formation with him. The only other Action ability that comes to mind is Daredevil and that isn't going to help much. All in all I think you're better of with PTL for now, at least until there's some modification that requires an action. As of now EI seams to only make sense on XY and passenger ships, and Tycho of course.

Tycho PTL Daredevil Interface?

This or expert handling, yeah. Dat 225 degree turning radius

Dat 2 Dice attack

The only thing I see being an iteresting option for Soontir with EI is Expose. 5 dice at range one... Unfortunately, he does care about the loss of agility. How about:

Soontir, EI, Royal Guard TIE, Expose, Stealth Device

37 points and you lose the barrel roll + boost combo... But 4-5 focussed attack dice...

Boost, Barrel Roll and Focus in one turn is what makes Soontir Soontir. Buying Expert Handling and Experimental Interface just to negate an enemy target lock is pointless though. It costs you 3pts and strongarms you into having to Boost before you Barrel Roll. Likewise using Expose as suggested above takes away from Soontir's game; 5 is great, but having 2-3 agility right in front of the enemy won't help him one bit.

Fel + daredevil + experimental interface + targeting computer.... Fel can boost/target lock / barrel roll and then daredevil, for double focus tokens. Now, you've got a stress problem - but that's what wingman or Captn Yorr is for.

As has been pointed out, PTL + TC allows the same suite of actions (and more) and is less limiting in order and type.

Tycho PTL Daredevil Interface?

This or expert handling, yeah. Dat 225 degree turning radius

Just wanna point out that Tycho plus Daredevil doesn't work. Sure you can perform actions, but performing a red maneuver within that action is not covered by his ability.

I tried to make Experimental Interface work on Soontir but for now, you're still better with PtL. Squad Leader is the closest to good I found but I consider that you would still be better off with Vader for this role.

The 2 things with EI is that first, it is the same cost as PtL but require you to buy a second EPT so you can use it, so it's not just 3 points but 5-7 points. Second, it doesn't give the freedom to pick the actions you want in the order you want. You have to take the action from an upgrade card, and it must be the second one you take.

With an Interceptor that action economy is everything, limiting the actions he can take and the order in which he can take them can be very detrimental. I think EI fits more on ships with a currently low action bar and design around an upgrade card more than a pilot. EI so you can use Expose or Markmanship every turn is fine; EI so you can have a stress token every turn, not so much.

check the errata on daredevil - it's now a white maneuver that gives a stress afterwards, Tycho can totally daredevil now

...and Target Lock + focus every turn.

No, he can't. Not with Experimental Interface, anyway. Targeting Computer adds the Target Lock action to your action bar; the upgrade itself does not contain an action that you can trigger with Interface.

Yes, he can. By Target locking and then using EI for Expert Handling or what have you, he gains a stress so he also gains a focus. But at the end if the day, I agree, Push is the better investment.

Daredevil is the one card FFG errataed. It and all its reprints are now white maneuver, then receive a stress token. That's what's written on my copy.
