Get Arenal or Yee to make you something similar? I have had great luck with this concept. Find a board you like and talk to a shaper that you trust and spitball about (without naming the other shaper/model, I feel that is a bit odd) a board that will fill the niche and/or modification of a model they offer. Often, I end up with something that works. For me, it is often meeting with a shaper in person, describing the waves I surf, the hole in the quiver I am filling, and how I envision using the board. I have had good luck with Eric Christenson, Mike Griffin(definitely go and meet in person), and Mason Dyer when he was around.
