We already talked about this via plurk, but I just wanted to pop in here to say hi again and put in a couple thoughts since I"ve had time to think about it.

I am personally more partial to Greed 2.0 because of the way he develops from Ling's influence, but again, the whole problem with possible Lings wanting to app. Avoiding spoilers, he has some amazing moments at the very end of the series, so I recommend finishing the series before you make a decision.
