Having owned and ridden extensively both the Varsity and the Super Sport, I can say the Varsity is not all that different from the Super Sport in terms of ride quality. Bought the Varsity new back in 1971 and used it for commuting and short weekend trips. The Super Sport I bought new in 1975 and again used it for commuting and week long tours. Both good bikes requiring little maintenance to keep running well. The SS was about 8 pounds lighter than the Varsity, but it was not noticeable when riding or going up hill.
Today, should the opportunity present itself to get either one of these models, I'd do it just for the fun of it, but the price needs to be such that I could resell for the same money.
