I like the orange shoulder tang a lot, nice vibrant personality, and they are super cool to watch them change. 
 
If you go with any of the powder tangs, or the achilles, I would hope you can find one second hand. I so rarely hear of them doing well from LFS to tank. You need one like Marie's tang. 
 
What kind of Kole do you have? Yellow ring?
