I'm building a noserider longboard. I understand that increased tail rocker and decreased nose rocker can be helpful for noseriders but was wondering if you had some input.

It is popular to "Flip" a stock blank to increase the tail rocker and lessen the nose rocker. This is also called Reverse Rocker.

 A lot of guys just template the board with the at the tail of the blank if the outline fits.

We can easily build you a reverse rocker blank in any size if your outline templates don't fit on a stock blank that is flipped.
