Light side Arena Store characters

DarkDave

Now that I have my Darth Sidious to 7*, I want to use my Arena Store tokens to bolster my Light side squad. What character should I spend them on? I currently have CUP at 2* but I am not sure if he is the direction to go with the tokens. Any thoughts on the others, ie Upnaught, Eeth Koth, Stormtrooper Han or Admiral Ackbar? My current light siders are:

Luminara 6*
Chewbacca 5*
Jedi Consular 4*
Luke Skywalker 4*
Poe Dameron 4*
Jawa 4*
Ewok Scout 2*
Ewok Elder 2*
Teebo 2*
Clone Sgt 2*
CUP 2*
Biggs 2*

I really like ST Han as my Arena tank. His turn meter abilities and 2-turn taunt are pretty nice. He is a little squishy but can usually survive the first round. Get a heal off and he's golden usually.
