I agree with Jim but would add a bit.
Depending on the size of the tower and length of the temporary guy my
Synthetic and Hemp rope both have their good and bad sides. Both age,
Nylon is a waste of time and dangerous due to the tremendous stretch.
On the 45G I used wire rope for the temporary guys.
On the 25G which will only go to 50 feet I'm using a Dacron double braid
which has very little stretch. The permanent guys will be Phillystran.
The small Phillystran makes excellent temporary guys, but it's kinda
pricey compared to 3/16" wire rope.
When using temporary guys I install the permanent guys as soon as I
reach that height. Each new section goes up with the temporary guys
attached to the top of it and they are tensioned before I go up that
one. With larger, stronger towers that likely would not be necessary but
Jim works with that size stuff, I don't.
Basically I'm using the Dacron instead of the wire rope as I gave away
the wire rope after finishing the 45G and before I'd decided to put up
the 25G AND I have about 1500 feet of the Dacron.
Temporary guys are often a necessity, but your neck or whoever else
might climb the tower depends on those temporary guys so choose and use
