I had problems with seats on my last 2 Road Kings and I bit the bullet and bought Corbin seats. I went through 3 seats on the 09 RK before I spent the bucks for the Corbin seat. Had the stock seat, then had that reworked, then bought a HD Sundowner seat. The Corbin seats are amazing as far as I'm concerned. When you first sit on one you swear that it is going to be too hard. Wrong! They don't take long to break in and I have been known to ride 8 or more hours on one with only gas stops and I didn't get off the bike for gas (only to use the can). Too bad you can't just try one for a few days instead of gambling all that money that you will like it.
Just my 2 cents.
