To my way of thinking, using a single piece of wood in a neck,flatsawn,quartersawn or otherwise,is like leaving it up to chance that Mother Nature will be in a cooperative mood and allow that piece of wood to do what you want it to, not just now, but for years to come ,in all kinds of environments and constantly changing climatic conditions. Laminating a neck with multiple pieces and types of wood will most assuredly increase the strength and stiffness of the neck (not to mention the various tonal possibilities),and allow the neck to move in a somewhat predictable manner.I read all the time about Alembics that were built in the 70's that still feel and play great. On the other hand, if you like dealing with dead spots on your finger board,there are plenty,(read too many)Fender and Fender clone one piece necks out there. Mike
