Okay, Pete -

   Your plan to use the 40M element is a good one; the buzz is that even the
single element for 40 works well.  
   To be honest with you, it would have to be some sort of emergency for me
to repair antennas in the air.  I much prefer ground level but for the 40M
single element, you could assemble it on the ground (for measurements, etc.)
and then bring it up.  Since it doesn't weigh much, one or two people on the
tower could handle it.  Since F12 uses bent pieces of aluminum that are flat
on the top for their element to boom brackets, you could bring up the bracket
BEFORE you assemble the element and predrill all the starter holes or at
least mark them while using a small bubble level on top of the bracket to
give you horizontal plumb.  That'll probably work assuming that the antenna
is horizontally plumb to begin with.  Unless you're really after +/- 0
degrees to the horizon, a couple of degrees out one way or another is only an
aesthetic problem (here in Washington our bottom line is "will the JA's
notice any difference?"
