This topic has been covered many times on this list. My tower
manufacturer recommends guying their self supporting towers. So in this
case do what the manufacturer says - guy.
I'll run the race and I will never be the same again.
The thing that makes a self supporting tower self supporting is the big
block of rebar reinforced concrete under it. Adding guys to a self
supporting tower may actually make it fail because of loads introduced
by the guys that were never intended by the manufacturer.
When the wind blows across guys, that force is transferred as a downward
force through the tower to the base. Rohn 25/45/55 were designed to be
guyed. I'm quite sure the Heights aluminum tower was not.
As the list moderator is so fond of saying "do what the manufacturer
says to do".
