I had the same experience as gb, found one for a fair price but with shipping and having to buy the STC I wasn't going to save much so I passed on it.
Agree Hoeschen, it's a lot of change just to put a bigger set of tires on. Does a guy really need them or just need to be one of the boys.

Not wanting to get too far off topic, but lately I have been seriously considering taking the 29" Airstreaks off the S7 and going to the8.50 smoothies made by Desser (MTV, I spelled it right this time!).

I had the 26" AIrstreaks and to be honest, they were about the perfect size on the RANS. Most of my so called 'back country flying' has been to friends strips or places that really don't need the big tires. The cost of the Bushwheels is considerable and I would rather save them for the time in the future that I need them. Besides, those big tires add quite a bit of weight.
