Need a suggestion for a leader

Illuminati

I usually rank top 20 in my arena but think I could do better not sure if I'm using the best combination of characters.

My current arena set up:

Ima gun di (leader)
Old Ben
Luminara
Barris
Consular


Here is the rest that I am not using http://imgur.com/ogWe3Jz

Illuminati

I also have 4* mace windu who I haven't even leveled yet.

Time

I'd consider dropping consular for a dps, sid could work.

Illuminati

If I replace consular with sid would it be better to change the leader to sid or barris?
