That curl that looks so amazing....that's wild grain in the wood. The reason it looks so amazing is because you are cutting across the grain VERY often. While grain violations are not as important on the belly as they are on the back, they are still relevant. And every grain violation is yet another opportunity for something to go wrong. But having no firsthand experience, I am only offering what I extrapolate from what other experience I have had with wood.
I'd love to be proven wrong on this one, though. Being a flintlock shooter, I have a love of curly maple deep in my DNA!
