I'm hardly the expert (I started this thread!), but I know that solid pieces
of wood, especially the Spitfire/GT6 shapes, would be highly susceptible to
warping. I used to work for a cabinetmaker, and down here where I live in
the Deep South, I know that solid hardwoods are not very "stable" because of
the extreme changes in humidity. Others may have had experiences that
contradict that, but depending on the climate where you live, I would think
it would certainly be something to consider.
