GL Counter with Vader Help Needed

I'm trying to build a GL counter with vader. I'm currently running an offense/potency set with CD triangle and potency cross. I'm searching the Internet for help and I see soooo many different comps and leads for different teams (mostly Rey) and, to my understanding, there is no one size fits all team.

I need help figuring out which lead to use (and allies) depending on my mods, as well as depending on which enemies are present. I am a low enough GP to where if I were to encounter a GL, it would only be one, so I would like my vader to be able to counter every GL for the time being. Which allies should I use alongside Vader and Thrawn? I have Traya 7 star, Wat 5 star, Shoretrooper 7 star, I'm working on Piett, I don't want to use BSF. What mods should I have on everyone? I know this is a lot to ask, but I would appreciate any help.
