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.
