I know this is kind of out of the box thinking but I was putting a lot of miles on my bike recently and I was stating to get but sores. So I bought a cheap gel car seat pad from Canadian Tire for $10 and it works amazingly well. One side is smooth and gives me standard gel comfort. The other side has big gaps in it for air flow and pointy tops. Every now and then I just flip it over and it's amazing. Never slips never moves just works very well. I know it's not a new bike seat but for 10 bucks it was a really solid decision.
