Decided to get the Kawasaki 'plain' gel seat for my 2012 900 Custom... Initial impression was that it was firmer, lower, and had more support for my lower back/tailbone. After a solid 2 hour ride today I really don't see any improvement over the stock seat. The ads I read for it say that there's no break in for it but I'm really hoping they're wrong. Going to give it a few more rides to decide whether or not to put it on Ebay and go buy a Mustang seat.
