As you speak about a sport tourer I can tell you I had one (ST1300) and now ride the F6b. I am 61 years old and just over 6 feet tall. I have a much easier time backing the F6b than the ST1300 because with the lower seat I get more torque with my legs. I really don't ever feel a need for reverse. By the way, you are correct in thinking the F6b would be more comfortable for longer rides. Putting forward pegs on the F6b added even more comfort.
