Airhawks serve a good purpose, but they are very expensive. I bought one several years ago and ended up using it at work more than on my bike and over time the thin walled air pockets started wearing through and after many patch attempts, some good some not, I threw it on the used gear pile. Last summer I bought a copy cat air pad on amazon, didn't even have a name, for less than half the cost of an Airhawk. It claimed thicker membrane, and it is, and I used it on my Texas to Alaska trip last fall. It literally saved my arse. Highly recommend for extended trips. As far as daily use on a Bobber, probably not worth the trouble. If you plan to take your Bobber out of town an air pad would probably worth taking along. The key is to run as little air as possible to just give your rear a layer of air between it and the seat. As eisen77 pointed out, even with minimal air you can get the sensation of swaying, I got used to it but it can be a bit annoying.
