I'm in my 80's, and I use a "cowboy" mount & dismount to help me clear the seat. That extra 6" makes such a difference that I use that mount almost exclusively. The rolling dismount takes a little more room, and practice -- but has the same advantage. If I'm stopped in a crowded area I just step a little farther away from the bike (than I.did 30 years ago), and just lean it toward me enough that I can clear the seat w/o giving away my age.
