That first squad looks VERY familiar.
I decimated our local play group with almost that exact same squad, but with Holo Veers instead of the Storm Commando. I found as I thought about the squad, that I would typically be using Thrawn to swap Evo Troopers into place for 40 damage shots, rather than putting the Storm Commando in place. You'll probably have one chance where you'll swap the SC in at the beginning of a round for his 60 damage, and then your opponent will kill the SC. I found that Holo Veers, combined with Thrawn's ysalimiri bubble wreaked havoc on my opponent's for the evening. Granted, it's quite luck based, but the guaranteed 10 damage, against any units within 2 squares of your target, ends up being great for taking out general scrubs/activations, or things like Ugnaughts.
The second squad definitely looks nasty as well. Just hope you don't roll 1's when you really don't want them.
