Let me restate the question

Hi John

Keeping the laminations all in same direction is an idea that goes other 
directions then worrying about cracks.

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.

Cheers
