Here we go again!! This is a cut and past from a post I did a few months ago. This is just my experience on the Valhalla, your mileage may vary!!
I rode the board a few weeks ago and I can assure you that if you have any wakeboarding skills, the Crook fins will not cause you to catch an edge or do a facial.
As far as the Crook fins being sharp and dangerous, they arenít sharp at all. The edge of the fin is rounded over and is no more dangerous then the edge of your board.
The time I noticed the Crook fins was when I put the board on edge and headed for the wake. It really allowed me to bury the edge and cut hard without the board wanting to break loose.
I also noticed the fins when I would over rotate tricks that usually result in a butt-check and the board sliding out. I remember on one toe side back roll I got more air then usual and over rotated and I thought for sure the board was going to slide out, but the Crook fins on my heel side edge stuck in the water and allowed me to stop the rotation and stand it up.
As far as the ride of the board, I would say if you like a fast board with great pop that tracks well when on edge, is loose when flat and lands really soft, then check it out.
