I think you're right Jeff. I never expected to see winds in excess 
of 60 mph here and that only on rare occasions, say once every five 
years or so. Yesterday I recorded 70 mph gusts. For a while I 
thought the TH-11DX, 6 meter long yagi and 2 meter long yagi would 
surely rip apart, or the mast would bend, or even the whole 
(overloaded) tower come down. I was very lucky! It's all up and 
nothing broken! Two of the antennas slipped on the mast and the mast 
slipped in the rotator but that is minor. I am of the "don't believe 
in pinning" camp as I suspect unless one has REALLY heavy duty stuff 
it only leads to more catastrophic damage.
