Ray,
I read somewhere a while back that the only real 'difference' between the various grades of Whiting capes and saddles had to do with feather count and size range...the 'higher' grades had more feathers and more of different (primarily smaller) sizes. The 'quality' of the individual feathers was the same.
Thus, if they were speaking the truth, then the Cabela's 'Whiting' capes whould be of that same awesome Whting quality. It's just the feather count that you don't 'know' from the catalog description.
I'm not sure if this helps. I don't know how to find out where they would rank in the Whiting 'scale'.
