I think I would also vote for Velvia as a transparency film, although as I shoot film for scanning I go for Kodak Portra 160 VC negative film.

If you are an infrequent landscape shooter, I would remind you of the saying "Don't shoot the landscape, shoot the light!" Any attempt to follow this principle will involve getting up EARLY - how this will sit with your first romantic break in years, I don't know!
