Thanks for this piece of info, I did not realize this.

The 55g @160' has 23.3 feet of windload, but the SSV only can suppot 8.3 feet.
The 55g is all most half as much money for twice the load! Knowing we don't
have to guy to 80% might make this work. I think we might have enough room
to guy out to 50%-60% of the tower length.
Better to have somthing over engineered for the the job than have it fall down
with me on it!
