Just throwing this out there for conversation points... but what about the following trio?
Excellent Endurance - I think we can all agree on this.
Kamikaze Attack - I think we are all ok with this from a flavor perspective
Press the Attack - Use this instead of Harass from a Distance... nothing says it can't be used with the Kamikaze Attack. At least you can possibly still make the Kamikaze Attack if a ship aborts it. It helps build synergy between the SAs, and can be used multiple times.
Just a thought... I think the PtA would be a cheaper option than HfaD, keeping the points down and making it different from other units due to the PtA synergy.
