I went ahead and buy the used 722 from craiglist. The frame has slight scratches but nothing major. His fork is cheap steel fork that actually has some dings and it's mismatched. So now I'm going to change it up, my questions are:

Which carbon fork fits better the I803 or the S805? I dislike the thick blades and prefer a more traditional tapered looking blade common on steel forks. Also wanted to make sure that the new fork I get isn't oversized like some Leader forks that are made specifically for the oversized headtube 725/735.

And was thinking while I'm at it, I'll get a new headset. I'm thinking Cane Creek 40 Series, would that work and fit on the 722 combined with either the I803 or S805 carbon fork?
