Good Lord! No wonder they're so expensive.

The boards I have are the stock, short stubby boards. I'm guessing most anything would be an improvement so I see me laminating some cheap, throw-away plywood, shaping it with a rasp until it's time for a nap. Then, if that shows any improvement while actually sailing, I'll make a set out of better materials.

Bless all of you willing to go through the complexity of engineering. It definitely ain't me!
