I personally ghost my scout but that is only so I can fit it on my Emerald when I do AA. I had it full of experts but it was too heavy for the Emmy so I just burned almost all the experts. Vets, Experts, and Rookies give AAW resistance. I don't find the resistance a problem... All you have to do is fly your scout at max altitude if crossing over a ship and I keep it at a lower altitude when I am having it watch a certain ship.
--EDIT-- And about the cap... I don't think the cap does anything but give full AAW immunity. Not 100% sure though.
