Bruce that may have been true with earlier versions of PS. CS5 and 6 have a different set of algorithms and uprezzing in larger increments doesn't have the problems it use to. If he ran 2 up he could try both methods of uprezzing or, given the viewing distance for a print that size try one uprezzed and one at 150. It's surprised me before when I thought it would look like garbage came out great.
