hi sabs shinn boards have benn doing a female specific board for a few years now check out shinnworld .com , some boards hold better than others so i dont take too much notice on sizes i look at the outline and the ability to hold an edge , ive seen riders with larger boards coping better than their smaller boards due to an agressive outline and big rocker, im currently trialing a 47 inch wide new concept board that is one of the best edging and gripping boards ive ridden
