Does anyone know if the neck shape is more "C" than "D" or the other way round. I have small hands and want a very "C" shape neck for comfort. Was wondering on the signature models if I can have a "shallow C shape" if that makes any sense. I'd love to hear thoughts and ideas on this and does Roscoe accommodate these type of requests. BTW, am I on the right track as far as neck shape is concerned for somebody with small hands wanting a comfortable neck??
