Yes they do suck.
Im not saying there are no forces, and I prefer to have my paddles aligned. But when my paddles are sitting on the ground, in between paddles, the tire is not sitting only on the space between the paddles, but also the 2 adjacent paddles. And thats on pavement, sand is a lot softer than pavement. You are never going to be pulling on one paddle on one tire and absolutely none on the other. Unless, like I said, you had very few paddles for the diameter of your tire.
Right now I am running 10 paddle extremes on a 20" tire. The carcass of the tire hardly even touches pavement, so you are definitely not going to be pulling on one paddle at a time on those.
But anyways, this is just nitpicking. I prefer to have my paddles aligned, it rides smoother on pavement and it looks better.
