That's a lot of AA dice for those squads... a little unprecedented too. Armada squads have only gone up to four dice on the AA rating... I wouldn't go much further than that. Trek Attack Wing severely disrupted the balance set down by X-Wing and it ended up as a huge mess of a balance problem.
Black dice have the highest percentage of hitting things, so Black dice is usually the best on AA rolls. However, they don't have accuracy to take on Aces. Red dice are too fickle to rely on, but their two-hit result can be surprising. None of the FFG fighters use red dice.
I was a little surprised you gave the core fighters the beam Keyword... I would have saved it for any beam weapons the size of a beam rifle or higher. Do Core booster beam weapons come with that heavy of a beam armament? Id' probably increase their bomber capacity as a result, rather than give them high AA. Beam-carrying High AA units should be other mobile suits, since they can fight with them in close quarters. Fighters are obsolete for a reason in the world of Mobile Suits, after all.
Remember as well that all squadrons only attack targets at range 1 (Unless they have an exception, like Rhymer). So the color of the dice doesn't matter for range, just results.
