On my '08 Road Glide - Mustang rider solo with backrest, and separate passenger wide saddle with HD detachable backrest. Passenger set up replaced with HD detachable fender rack when riding solo. I very much like the look, comfort,and versatility.
On my '00 Deuce - Corbin solo with backrest. I also have a Corbin big two-up touring saddle for the Deuce that I don't use any more since buying the FLTR. Back rest is interchangeable between both Corbin saddles. Great saddle and backrest for short rides; gives a sense of connection and control of bike.
I prefer the Glide and Mustang saddle for rides over 150 miles. Deuce w Corbin is in its element in urban traffic and hopping.
