I chose the rating as this i found has a serious design floor. The rubber hoops for your feet pass through to the underside of the board, becoming snagged in the snow and so slowing sometimes stopping you! However i solved the problem by buying a sheet of vinyl from the poundshop! Im sure gluing them in would also solve the problem!
it is also a very short board, or im tall (6ft 4) feels short but is still a good little board to mess around on and ruin!
