I get all that, I've been riding for quite some time and sell this snowboard stuff. I'm not new to the nuances of snowboards.
No, you can't compare numbers between companies. An experienced rider can compare in a companies line. They call their stiffest boards 7's. So to call the Whatever a 7 to me just seems wrong. It is not near the stiffness of a Jam or Undisputed.
It felt to me just shy of mid-stiff for a park board in a 153 and I weigh 145. So in that case to say that it ranks with the stiffest of the rest of the Bataleon line just doesn't add up.
That thing I do to escape the world and have fun with my friends
