What makes the second method any easier than the first? You still have to
get the mast up high enough to get it into the tower, either way -- you're
just closer to the ground when you do it the second way (though the
difference between getting conked on the coconut with a mast from 20' or
200' probably isn't worth mentioning!).

And, you still have to haul the mast up to the top, regardless.
