now I'm on the hunt for something that'll fit my RF...other than the corbin

If you haven't tried a Corbin on your RF900, you should. I had one on my RF900 and it was just fantastic. I rode many thousands of miles on that bike/seat. I only wish the Corbins I've had on other bikes were as good as the one on my RF.
Another option out there was a gel seat made for the RF by Saddleman (I think). It was an original Suzuki accessory. More rare than hen's teeth, but something you can look out for. I had one once and tried it vs. the Corbin, but preferred the Corbin (even if it was as heavy as a damned cinder block).
