A data point. I had an inverted vee at 60 feet, using irrigation
tubing. The bottom 30 ft was 3 inch O.D., and the top 30 ft was 2 inch
O.D. Wall thickness was 0.050 inch. This is about the flimsiest
that I would recommend. It wiggled around quite a bit in 70+ MPH winds,
but never fell down. It had 4 way guying at the top and another
set of guys halfway up. Additional guying wouldn't have hurt.
I am currently using 3 inch for the whole 60 feet. I'm not worried
about that at all in the wind. OTOH, those tapered verticals I would
worry about a lot.
