| I find 3Cers in the GR fraternity that consider a 66 to be the equivalent to a 3C, while others think that either the 65 or 67 is just right. Those are small differences, but it really gets down to feel. If you thought a 66 was a little two narrow, then the 67 may be the ticket.
If you're speaking only as to the rim contour (I think that the two parameters need to be considered together), then the *** or some of the other Signature pieces might be more to your liking.
Personally, I like the bite of the stock GR rim combined with the slipperyness of gold plate.
