@kent1969. I was thinking about getting a backrest when I was using the Corbin seat (has a built-in place for a backrest). Unfortunately that would have done nothing for my tailbone - which was the biggest culprit on the Corbin. Hopefully the taller, flatter surface of the stock seat (along w/ my mid-pegs) will fix that problem. If my lower back still gives me problems I might have to get a backrest - tho I will likely build my own as I am not a fan of the looks of the protac.
