Hmm, I'm not sure what the question is. Of course the tension figures you
mentioned are correct. Use the 10% spec for all guys regardless of size or
location. Leg strength is the limiting factor for tower strength but the forces
from 85 feet of 45G are relatively small in the overall scheme of things so
the additional guy tension will have little or no effect on the tower
reliability.
A LOOS tension gauge makes getting the tensions correct a slamdunk.
