If my feeble memory serves me, I'm in an 80 Mph zone. In the past year
alone, we have had two occasions of officially recorded straight-line blasts
of over 90 mph (recorded at the airport about 4 miles east of me). The last
one took down a dozen or so very large trees around my place, and ripped out
about 100 feet of split rail fence. So charts be damned, I built my recently
erected guyed R45 to Rohn's 110 mph specs. Total added cost to get from 80
to 110, as far as I can figure, is about $75 worth of extra concrete, some
extra sweat in digging larger anchor holes, and an added $100 or so more to
buy 4130N mast material vice something a little more bendable.  I'd go for
the overkill on the wind speed rating, and give up a little tower height to
do it if necessary. You'll sleep better at night, I promise.
73, Jerry W5KP
