I own two other DK-specific boards for comparison. This board is plenty stiff for the knee with a stable outline that is wider toward the tail than some of my other boards. I really dig the double concave bottom and vax trax rails. I wanted to try something unique and different that isn't just a gimmick and this board delivered. It holds a line very well and releases when you want it to. The slick did arrive with some scratches that looked like they had to have happened at the factory even before the clear plastic wrap was applied, not during shipping, but this board was on sale for $106 off so that is fair. I really value DK boards that try to push innovation and this one is a winner for me. Also Nick Gornall rips.
