Early speedboats, airplanes, and race cars used wood for good reason -- high strength to weight. I think balsa is still in high demand for wind turbine blades. But wood is difficult to use in mass production situation, due to its variable characteristics. Lee -- Excellence does not require perfection. -- Henry James -- Lee A.
