I have a Danny Gray big seat on my 07 FLHRC with the optional pillion pad and love it.Even though it is firm,on a long ride it is much more comfortable than my HD pillow look touring seat,don't get those pressre point sore spots.
I put a Lepara Bare Bones solo seat on my 07 flhx and I love it. It is a model for a road king but it fits perfectly. Its really comfortable even on long rides.
