The greatest loads that the tower will see are the overturning moments from
wind... (We had a recorded 93mph gust in a thunderstorm 3 weeks ago) ...
Therefore, you always put the top guy attachment point as high as possible,
especially where you have a mast extension above the tower... Then, if the
torquing moments are causing tower twisting that is alarming or
unacceptable you will have to add torque arms and a vee bridle at the rotor
level...
