We own a Steel Burley Duet that we rode for about 10 years. We loved it until we bought our Aluminum Santana Sovering. Besides several pounds of weight difference, the Santana handles, feels, climbs, etc. etc. much better. The stoker comfort is not an issue, since the Santana came equiped with suspension seat post... my stoker refuses to ride without one... you won't have to worry about calling: BUMP!! Which ever way you go make sure to get a suspension seat post.
