I beg to differ. The function of sensible guying is to prevent the tower
from reaching its material failure point, or at least delay it.

on the contrary, the function of guys IS to make the system stronger. After
all, you do guy Rohn 25/45/55 don't you? Sensible guying here, and
elsewhere, will increase the load rating and produce later failure.
