With all due respects, that is B.S. When I finally took my 63 ft verticals
down, I untied the last remaining guys, the ones that were at the 35' level
and jumped back thinking they would come crashing down. To my surprise,
they stayed up. Since I was not going to take the tubing with me, I grabbed
one of the top guys and pulled. The damn things didn't buckle until the
tips were close to the ground. Maybe this was because I had sleeved them
internally with some steel conduit for the first 6 feet. True story.
