Without any AP *and* with Slow Load, I just can't get behind the standard Avioki, and certainly not the Tashkat. Their weapons just plain miss...unless all you want to kill are enemy Skirmishers.
Neither seems worth their Pri Level, except in terms of Survivability.
During ACTA, I was ALL about a big Brakiri fleet. Then SFOS came out and, well, I'm not ordering that lot for sure. Sure, I could make something nifty with the Kaliva variants, Haliks, etc. But it stick in my craw when there's no reason to take a primary over a Variant. It bugs me enough with the Prefect vs Centurion deal, but no way I'll build a Brakiri fleet without an Avioki...
