I have them all- gel seat, airhawk, bead, sheepskin and none of them fixed the problem. The air hawk worked the best on my 2011 but not on my 2014, its more comfortable on its own. Also, anything on the seat cause loss of grip and I slide around too much on a tight corner.
Monkey Butt power works but I found that GoldBond Medicated Powerder works like magic. I put in my socks, my shorts (front and back) and my upper torso (front and back. It tingles just like they say and it absorbs the sweat and kills the itch and chaff. I need to apply several times, about every time I need a toilet or about every 3-4 hours apart. I now can do the entire day in the saddle with no discomfort at all.
Now, if you suffer from tailbone pain then you have a different problem but for what you described, try the Goldbond.
