I also was considering the new 2018/19 Goldwing (f6b) until several sources indicated no lower seat options were available to fit the frame changes for the newer models...I do have the Mustang seat on my 2013 F6b and taller 1/2"heels and soles on my riding boots and have no issues at all...I do like the option of the reverse gear on the new ones, but for over $13,000 and my current bike I will keep the 6 as it does almost everything I need and is paid for!!...Good luck on your choices.
