I am more than intrigued. Simon. Help me understand. You have a high crowned back. Do you pick a thickness of the limb for the edges and then hollow the belly out to keep the same thickness in the center where the thicker crown is? Then how do you tiller? Does this make the crowned back actually do some work? This makes more since that decrowning and having a feathered back that could be too weak when you leave the belly flat. I love it.
