Funny you ask this as I have been pondering the same myself. I have just shelled out for a AirHawk seat cover which seems somewhat weird to use but does feel to more comfortable than the standard seat. The Airhawk can be adjusted to suit your physionomy, but is probably better suited for long distance touring rides, rather than a quick nip to the shops. It has a strange feeling to it in that you do move around on it a bit but once you are used to this, it appears to deliver the goods. I still like ot know what the Corbin seat is like, so if you do get a response on this, let me know
