I'm going to be getting a 700 in the next few months and I'm going to need a good set of paddles. I don't drag race, I mostly do a lot of hillshooting, but also a lot of just general dune riding. I ride oregon dunes when the sand is wet, and I'm around 140lbs. I'm going to be getting a stock bike and most likely will never get any mods. There are 3 sizes I had in mind. 22x11-8, 20x11-10, and 21x12-8. Haulers or extremes? How many paddles? What is the biggest tire that will fit with the stock swing arm and not hit the stock heal guards? What do you run and how do you like it?
