I couldn't agree more. Unfortunately there is WAY too much tower between
the housebracket and the guys - 42 feet. The Rohn specs call for 32-34 feet
Why do I suspect that the guys were NOT 3/16" EHS like the specs call
for? Just a wild guess on my part.

They do well for amateur installations in spite of the many short-cuts
and back-of-the-envelope engineering hams are well known for.

I did - it's wrong. I just posted more specific information on "Tower
Buidling (sic) 201".
