laminated ribs

Just to revisit this for a moment--on an RC&S board do you find a
significant tonal difference between a board loaded at 250 and one loaded at
800 lbs?

Loading from about 0.75° in the low bass (which in my opinion 
isn't out of line for an RC&S board with a decent back scale 
length and no cantilever), to 1.75° at the top will put you in 
the 800lb range at 40,000 lbs overall tension. A low bass of 
0°, to a top end of 1° would get you a tad over 250 lbs, 
depending on tension distributions and such. I don't see a 
problem with the higher bearing figures with a rib scale 
designed to support it.
