yeah i say 10 or 12... oh yeah, your going to nee a drag axle, no matter what. you will break any other axle and hub that isnt heavy duty. i was building an r1 banshee, but now i want a plain banshee so i scratched the plans. but yeah at least a 10 over, and what kinda riding you gunna do in the sand? dragging or hillshooting, or just duning? i dont think 14 paddle extremes will be enough.. at all.
