Keith,
Take a look at slide #4 in the following presentation from
N6BV. It shows elevation plots for several different 80
meter antennas (including a 3 element Yagi at 200') along
with angle of arrival statistics derived from VOACAP:

Unless your concentrating on domestic operation out to
say less than a thousand miles, I'd don't think there would
be any performance advantage to going with the lower
height.
Nice problem to have. Enjoy!!
