I've had my 29" Bushwheels on the 180 for 10 years. I know how they work and what they'll do and I've enjoyed them but for all intents and purposes a set of 29x11x10 Air Hawks will do what I need so I'm considering them as a suitable alternative. The only thing I might give up is a little shock absorption and that's really not a big deal for me. I think I might appreciate some stiffer sidewalls and less lateral roll. I also think about dropping the 14" tailwheel to something shorter to improve the AOA. These are changes that make sense. Mission appropriate. Besides, I may just want to try something different.
