G'day Seadragonfoundry, welcome to the forum
I'm another one that tried a lot of seating options, airhawk, gel pads, corbin seat and a standard seat modified by an upholsterer (twice).
All of these options did improve the seat a little.
Then I was lucky enough to be able to try a ride on a mates Russel Daylong seat
WOW, it was a dramatic improvement (I had heard they were an good but I was blown away by just how much better it was)
The RDL seat was more comfortable and I didn't experience any sore/pressure spots.
After a few hours I still needed a break but when I got back on it was like getting on the bike for the first time that day
So when I had saved up the money I brought my own Russel Daylong seats
They are expensive at around $1000 for both front & rear seats but if you plan on riding your bike for some time to come it is well worth the money IMHO.
I've had mine for a few years now and still love them (The wife is also a big fan when riding pillion)
Cheers
Shiney
