BTW I might be wrong about carbon fiber masts, thinking about carbon fiber vaulting poles...
they don't make those out of aluminum. However the issue of low yield before failure *is* a

Doug, I believe that so called "Carbon Fiber" pole vault poles are actualy
a mixture of carbon and traditional glass.
