I have a RaceFace North Shore DH crank set up on my bike and have used, seen and compared it to the Prodigy DH cranks.... they are close to the same except for the North Shore one is machined, and the Prodigy is forged, they are just as burly as each other...
Don't get the Prodigy XC crank set, spend the little extra for the DH one (bash guard or not), but it also comes down to what kind of ridding you do?
I've seen those Prodigy DH cranks go through and over alot and am very impressed RaceFace makes very nice Cranks, rings and everything...
