Does anyone know how high they jack up the spoke tensions on some of those low count wheels?

I know a thicker spoke pulls harder than a thinner spoke at the same tension (am I right on this?)

I figure the next generation of Ksyriums will be 14/16 with bigger spokes.

BTW, for all those using regular hubs (non-straight pull) these are interesting. http://velocityusa.com/wheels/atb-zvino.php

True those are for ATB wheels, but something like that could be made available for road rims. Just use spokes with beefier elbows and spoke tensions could go higher.
