Meters; a 2 or 3 stack of medium - longer boom 10 meter beams, or just one
higher 10 Meter beam at maybe 120 - 140 feet?
Have you modeled it in TA? I think you'll find that a single yagi that
high is way too high for most conditions.
The secret to success on any band is to have multiple antennas for
that band. The advantage of a stack is that you get some cumulative gain when
used together plus it hears better because some of the nulls are filled in.
Do some antenna modeling for more details.
Multiple antennas will allow you to select different takeoff and
arrival angles and different headings with easy switching. As some 10M
contesters will attest, a 10M yagi at 30 can work like gangbusters. Ten-meter
contests have been won with low antennas like that.
