The mast for the original 6.0 is the same length as the NA. The difference is the diamonds(double vs. single) and the position of the Mast hound. The mast hound on the NA is approx. 2 ft. higher than on the original 6.0 mast.

I have already moved my hounds. Primarily for more leverage while on the wire. Also for using the stock (small) NA jib.
