All sand is not the same... fine sand, coarse, packed, dry, wet... Nor is the terrain... flat, small gentle dunes, monster dunes... Straight line or whatever?? Paddle tires are different also... angeled paddles, straight paddles, 8 paddles or 10?? Many variables. What it really come down to is what works best for YOU and where and how YOU are riding. Best advice is to be prepared to air up or down till you get to how YOU want it.
