Roho Airhawk
I have not had any experience with the Russell, but they look well constructed. In my search for a softer butt pad, the ROHO company impressed me with their technology and their supply to the medical and aviation fields. I have had an Airhawk (original model) for a few years now and so far my record is 760 miles in a single day. The Airhawk enabled me to get off the bike after that long ride and still feel reasonably good. It was much better (less fatigue) than just the standard touring seat. Another bonus in hot weather, the Airhawk runs cooler and you won't develop as much sweat as without. One drawback of the Airhawk is the elevated ride height and how it may affect the windscreen protection (rain, etc.) and on twisty roads the preference is have a lower riding position. In summary, if your planniing on riding longer distances (100+ miles), they save your ASS... and are well worth the money. Airhawk have released a version 2 (different construction) as a more economical alternative that delivers similar results. Hope this helps.
