so, I played this list last night, and it took about 2 hours to get towards the end of the game.

Ill go over most of the differences overall
A's are very similar to Interceptors with movement (with only a slightly better dial)
2 hull, 2 shields is a HUGE improvement (typically if something gets through, its only 1 hit, and theres a good chance it was a crit...)
Jake can be flown by an imperial player without realizing much of a difference, Tycho, is a different beast...
Lets start with Jake. Focus Barrel-roll, boost, stress (sounds like Sootnir, for a very good reason) Hes pilot skill 9, and I flew him toe to toe vs Sootnir last night. If you face a sootnir, your going to have to use your proton rocket, and can follow through the last bit of damage with another ship. I had Sootnir down to 1 hp, with lots of turtleing happening.
Jake by himself was a monster
Tycho... Tycho... Tycho... wow this is an amazing pilot, while you want to try keep the unexpected k turn boost focus option open, he fills up with stress as soon as you realize you need to hard 3 to cut around that asteroid a little bit more, or the hard 1 for a tighter placement (tailing an interceptor is pretty nice) There is allot that can be done with Tycho, and just collecting stress tokens is AOFF (allot of fricken fun)
Za Cracken!!!! Cracken was used as a support ship, and a distraction. He buffed Tycho and Jake for as long as he could (never used his rockets due to boosting for shots/arc jumping). Your opponnent has a range 1 on a focus undamged Jake, or a range 2 on a damaged cracken, tends to go for the crack first
He lets Jake take 3 actions without stressing (or take 4 and gain a stress).
And around Tycho, he gets all 4 of his actions, or you get a ps 10 Turr (shoot with tycho first, then shoot with cracken, boost out of the way with tycho)
