     This is a BIG drawback. You need to have excellent rigging skills and the
right tools in order to install safe temporary guys. These are rare
commodities in amateur circles. I discourage anyone from following this route
unless you have both. 

     For big tower loads, a pier pin base does an excellent job of equalizing
the compressive leg forces. (This may be somewhat illusory as the flat tower
base has to sit on the concrete pad which is never perfectly flat anyway.) For
relatively low to moderate tower sizes and loads (typical ham installation),
IMO it's not worth worrying about - put the bottom section in concrete and go
up from there. It's easier and safer.
