which fork

Hello all, 

So I recently found (ebay) a brand new still in the box team edition 2007 cannondale cx 7. I would like to put a carbon fork on it, it originally came with a fatty fork but i would like to upgrade a bit with carbon fork and some modern brakes, wheels, and groupset (1x10). Both forks that I have found made with 1 1/8 steering tubes are the Spot CX disk fork and the Ritchey CX disk, both look amazing, both are about the same price but which should I get? Or are there other options I haven't seen? 

Any advice or comments would be greatly appreciated. 

Mike
