Looking for opinions for farming Arena.. especially ST Han

I was just looking into this, Savage and Greedo look interesting to me... though I've never really been a big greedo fan. I play against STH and seem to have less of an issue with him now than I did before the update. HK-47 is too slow for the amount of damage dealt. I'm most of the way to having DS at 7* so I will complete him and then decide. Right now I'm leaning Savage though and will wait to hear opinions on Greedo from those that have him....

Will of course be watchful on STH.... I also won't need to be in any hurry and probably will stockpile some arena tokens for a few days as a wrong move precaution.
