I'm no engineer, either, but that fits my way of thinking too.

I'm biased, too, by a colleague with a tall tower and a big mask sticking
out the top.  He was a VHFer.

He got a fairly big storm.  The mast bent, but the tower (and even the
antennas) survived.  But, yeah, if I had a tall enough tower I'd give up
the mast and antennas instead of the tower if I could design that in
properly.  Guy the tower, give up the mast.
