When the wind is blowing at 80 mph, just think about what is at stake
out there, both financially and in the labor involved in replacement.
I don't think you want to be relying on seat-of-the-pants guesswork to
keep it all up. I'm not sure I would trust a local engineer to do the
calcs correctly, either, at least in my hick town. I think the best
solution is to stick with factory specs on a guyed or freestanding
tower, or to overload a crankup/pulldown tower and keep it cranked
down whenever there is the danger of a significant wind event. If you
can get the factory engineers to bless your guying of a freestander,
that's ok too.
