Has anyone used them? How well do they work on a big bore 4-stroke?

The "Ripper" is basically an extreme version of the Extreme paddle tire, and has paddles that are 1/8" taller and 1/8" thicker than the Extreme. Just wondering how they work.

 

gary at tvi runs them on his big ds, that is a lot of tire to turn. one of the guys i ride with has the 760 and he has 12 paddle taller haulers and we have found the 10 paddle to be faster all the way around. in the very loose sand they might have a edge
