215# on C35's and love them. Don't believe the "at your weight don't worry about cross wind" this is crap. I live in a windy area and I can tell you that I notice the winds effects on the 35's much more than the RXLTL Bontraggers on my Domane. I would not consider the 50's ever myself, 24's or 35's are your best bet. Fantastic wheels, smooth, fast and quiet to boot.
