Out of all my designs, this is by far my favorite to shape. I’ve been blessed to get the best feed back in the world by the best big wave surfers in the world allowing me to stay on top of the cutting edge of big wave equipment. We are using quads in clean and predictable conditions and tri fins with a slightly larger center fin in everything else cause they are more forgiving and stable. If you are only going to have one of these in your quiver I recommend ordering a tri fin. This board is not for the novice. Serious inquiries only please.
