I have thought about providing shaped blanks, but it becomes fairly costly. With the cost of cutting, shaping, and shipping the "blank", you are probably looking at >$200. Shipping alone is at least $60, the foam is another 50, shaping can range from $50-100, so it becomes somewhat undesirable to most customers.
We have traction pads that I would be happy to sell to you and others. They would be $75-100 each, but they are made for wakesurf and work really well. You can check out our instagram feed (@day1wake) for lots of pics.
If you wanted me to shape a blank, provide traction, and send to you, I could. I'm just not sure if the cost would be worth it to you. Would you also want me to cut and set the fin boxes?
Thanks for the questions, let me know if I can help.
