in my experience once you get above the tree line the
wind NEVER stops... i was amazed the first time i
worked on a 100+ footer it was really calm on the
ground but around 70-80 ft it was 15-20mph
constantly... just drop a light rope from the top and
watch the arc down to just below the average tree line
where it comes back into the tower...

just my .02/experience...
