Several good replies here.
I also ride the Oregon dunes and on the YFZ I use 20" X 10" X 10" 8 paddle haulers on 10" rims. For me the 10" rims give better side stability and I do a lot of side-hilling.
I don't think I'd go over 8 paddles on a stock Rappy. You can run more paddles, but sooner or later it becomes overkill (especially on a stock Rappy).

If price is a concern, I believe the above mentioned paddles are the cheapest ones as far as Haulers go? If not, then they are close to the cheapest ones for our application.
I think any of the above mentioned ones will work. The edge's are good paddle tires too, and may make turning a bit easier.
Oh, and congrats on the new Rappy! I am sure you are going to LOVE it!
