This was the first ever model done in Spine-tek technology and epoxy and it created HAVOK for me. I could not fathom how good this board went and it is the foundation for every other model in this range.
The formula was simple. I took 1/8 rocker out of the tail and 1/4 inch rocker out of the nose rocker to compensate for the flex and widened up the tail for more drive.
It has more width in the plan shape for smoother rail turns and fuller rails which make it super forgiving through turns. The HAVOK is ridden 1-2 inches shorter than your regular board and 1/4-1/2 inch wider.
