With the helpful information now received I want to know exactly what, and how much, is inside a board before I buy any more new ones? Fancy marketing pictures of hot shots doing twirly whirly things on 50 foot breaks, then throwing in a couple of loops while picking their noses in boredom at the lack of real action is useless. I want to see sectioned [nearly said exploded] diagrams of a boards innards. The thicknesses names and average densities of the materials used is also needed. In any other field [cars, cameras,etc] we get deluged with such information. Why not with boards? Iv'e spent thousands over the years so I feel justified in now making demands! P.S. I note that with carbon booms the strengh before lightness principle is the norm, but not with boards! Well, the worm has turned!!!!!!
