As I recall, Scott, KA9FOX and owner of QTH.com experienced a similar 
shearing issue that caused an upper section to bend on a Trylon T500-72 at 
his old QTH.    After that experience, he went with a guyed tower for his 
new QTH.

##  That 72 ft trylon is only rated for 6 sq ft  at 100 mph.  If you want the real deal, trylon makes
the heavy duty version, comes in 10 ft sections..and uses splice plates between sections, so no 
sectional overlaps.  The 72 ft trylon loses 4.5 inchs in the sectional overlaps..so its only really just over
69 ft tall.   The real deal trylon sself support towers are on their website.... and go up to 180 ft. 
You wont lift the sections on em with a gin pole though..way too heavy.   But if u want something that will
handle 50-75 sq ft plus an inch of ice, they work very well....and reasonably priced.   Sorta like an AN wireless
tower on steroids.
