The advantage of top loading for the 90 footer will almost
make up for the height advantage of the 120 footer.  The
structural degree of difficulty is much greater for 120
feet than 90 feet, so it would be hard to justify 120 feet.
If you have a good enough ground, there is no advantage
to the additional height (except greater BW).
