Wait a minute. When are you 'moving the temps up'? The sequence for Rohn
guyed tower of any caliber is to put up 4 sections, attach the permanent guys,
put up 4 more sections, attach guys, repeat as necessary. This means that you
can safely climb up to 4 sections of exposed tower. People do it every day.
If you are putting in temporary guys in the midst of these 4 section
erections, then you're doing it for psychological reasons. They really aren't
necessary. This also adds about twice as much time to do the job.

You check a tower for plumb and tension from the bottom up - not the
top down.
