I did #4. Although I do think that the blue and the black sleds are nice looking after seeing them at the Sneak Peek last night. We even interchanged some panels on the orange one (just like #4) with blue ones to get it that Boise State Broncos look. I may do that this year just for kicks!
#5, didn't want to deal with orange rails when they chip. With black, it's easier to touch up. I have a black 15, the side panels show every scratch! I'm done with black side panels, it does look really nice when new though.
