A further thought !

Changed from metal to fibreglass.  Made no detectable difference however
fibreglass is more flexible than metal.  My fibreglass boom flexes quite
a lot in high winds.  Perhaps this helps to absorb the wind energy and
protects my tower.

BTW  check that the fibreglass boom you buy has a good thick gel coat.
           (layer of clear resin put on after the last layer of glass mat)
           If its thin water will get in and destroy the mechanical
propeties
           over time. 

73  and all the best for New Year
