I'd put a smaller cassette and for sure get a short cage derailleur. I'd also look into Jagwire, they have some sweet blue stuff too. I'm about to do a blue/green build myself. I've got green/orange bike, a green/purple bike, a green/red bike, now all I need is the blue/green bike and I'll have the ninja turtles!!!
sick man! lower the top part of the chain guide as close to the ring ( i know its hard due to the frame and it being a small ring but will work better)
