I live a little further north than you and do similar riding as well. Maybe longer distances than you, but similar in any case. Given the choices you have, I would pick neither of them. Get a set of carbon 50+ mm in depth regardless of whether t is clincher or tubular. Your choice there. Many out to choose from ranging from the carbon wheels sold by bikeisland.com to Reynolds and everything in between. Many choices and a large price range. Narrow it more and we'll narrow more the recommendation.
