I use cruiser pro 145X48.
using CrazyFly sculp size11 + Cruiser Pro 145X48 you can go up wind @ about 11 Knots.
you can use this board as well at higher wind, I use it at 17K but obviously at those kind of wind you can have fun with your regular board .
realy good board, very somth and esay to twist to toe side and back.
here some action of my friend @ high wind with this board
and here some light wind action, if you can call this action
