Imp Aces or Brobots
In my opinion (which isn't worth much!) Push the Limit on the Inquisitor and Autothrusters on both Aggressors are the 'mandatory' changes you'd be looking to start with. What upgrades do you have? If you have a Heavy Laser Cannon that is golden on an IG, then swap out IG-88D for IG-88B. This will give you more 'punch' on at least one ship in case not every list you come up against is a Palp Ace's list.
Also on the first list that's a lot of ordnance on a six health ship. Maybe re-arm Tomax a little and that will free up some points to spend on the inquisitor. Without the ability to 'turtle' (take focus and evade tokens for defence) he'll go 'pop' pretty quickly too.
I'm not well-versed at Aces but I enjoy using Brobots. I think that even without HLC, you would still be better off using IG-88B instead of D if you're using the autoblasters.
thanks guy I will try your suggestions next week at my local club
