I thought Ron answered the question. You can achieve whatever crown you want. The issue of why grain angles are chosen in order to increase or reduce stiffness in the treble versus the bass area because of the angle of the bridges relative to the grain is another matter.

What I was curious about and still havent gotten a straight up answer too, is whether or not a laminate board laminated over a curved caul with the grain all going in the same direction could achieve the same crown and crown support as a ribbed board with ribs going perpendicular to the grain. I.e. the strength of the laminant panel along the grain compared to the strength of the ribbed board along the ribs.
