The momentum squad has huge problems. First, no R2 Astromech Droid. There is literally no reason to leave him out. He is arguably the best 9 points you can spend in the entire game. Second, too many commanders and not enough attackers. Once Dash dies your damage output plummets to not enough, and without swap or towing or really any tech at all, your opponent will be able to kill Dash most of the time. Flobi and Skywalker are both much too easy to kill to serve as your primary beatsticks or to try and block all your opponent's firepower (once Flobi runs out of Force points, he's in trouble even against shooting). Plus if you have to face Kyle Katarn, which is VERY LIKELY, your squad falls apart because without CEs you can't really hurt him without risking the very pieces that are providing the CEs to begin with.

The NR squad with Jaina just doesn't make sense. You use Jaina to bring in a Han who has cunning attack, instead of just using the NR Han who has cunning attack who is also better in every way. You use Wedge Antilles, but the only pieces he benefits are scrubs, Jaina, and Mara Jade, who has stealth. He is just a waste of points with that build. And you have a Czerka to give Han jolt and the Vigo twin? Those are nice to have, but worth 13 easy-to-kill points? And the TBSV is only in there to begin with to give Jaina GMA? It's just a mess.

The opportunist(?) squad is equally strange. No Wedge, which is fine, but a Corellian Security Officer who pumps up one Jawa scavenger? Why is he in there? Why are you trying to build a squad around Vigos shooting with opportunist to begin with? If you really want to do that, you're in the wrong faction. Kol is good and Han is good, but after that nothing makes very much sense.

I disagree NR vigos can work. I did well with a weird version around IE with Xizor and the CSO. They are 17 for 50 twin vs 17 for 40 double twin. But there are reasons to run NR vigos over Imps. NR have mid cost beats like kyp and now they have Ganner. They have disruptive in Talon. The last part you can use dod over ozzel so odds are you will get opp. So because of this its about the same damage output and you can fit in a beat. Kol or kyp work. You can use some ABSV for cunning. Yes I know all of this was before yodabuck and the lancer were really around. I was using some kel dors or talon to help with that problem. I do like kyp or even leia with the vigos.

I would just go straight shooter and take out kol for more vigos. You do have a enough damage output to shot GOWK to death it just comes down to the rolls.

In the Mara Jedi I might go Ganner. I dont see why wedge and the TBSV are really that much better than Ganner. Your trying to use mara as your beat so why not get as much speed as you can to get her in there. once she is in there she is going to die.

Republic squad
Before the Obi errata that type of squad was one of the best around. I would take out obi and work in some other things that work with Gen skywalker.
obi padwan
dark woman
JWM
Ferus
Geo assassin
Yodabuck
Jax for 16 points is not bad
