That's what I was thinking. '71' isn't really a very revelent factor. Without knowing a lot more about the overall health and condition of the rider, his past riding experience and where and how he likes to ride, I don't see how anybody could make a very valid recommendation.
A common recommendation, that I think is particularly true before buying a recumbent, is to test ride a few different styles. Even before offering a test ride, however, a competent bike shop person will probably have a lot of questions about your past riding history and future riding asperations.
