gel pad worked for me on long trips and I got that thin seat that came on CVO Fatboy

 

I noticed that I was getting a pressure pain in my tailbone from sitting on my 06 Fatboy stock seat. Didn't need to be a long ride either...could be just a short 30 min ride and I would notice this.

I like the look of stock seat, so before I spent the bucks on a different seat, I decided to have a a 'Butt Buffer' installed into the seat. All in, it came to about $250 CDN with shipping. (I did it early in the season because I needed to ship the seat to Butt Buffer's Canadian location to have it installed. The seat was gone for about 10 days total time.)

I didn't notice any substantially different feel to the seat when I got it back, but I am happy to report that I have not experienced the tailbone pressure pain since the Butt Buffer was installed. I've put ~1500 miles on the bike since then.
