It will make all the difference. I never been in sand, we ride alot of woods, mostly steep hills, rocky steep hills, and oh yea steep hills. I wouldn't go back to 14T for it. It bogs too much, too much clutch work, and I also have the big 3 and pciii, and a uni with my own lid mod.Nope not at all. But I think it would be better with a 13t if you stay with stock exhaust and stuff. The sand was pretty damp yesterday and it still turned them pretty good.You maybe even could have gotten by with knobs instead of paddles. This thing has plenty of torque to turn the 22's. It still wants to stall somewhat if you don't get it going though. I believe that the 13t front gear will take care of that somewhat too.
