MUDDOG7375,
One of the better guides I've run on to has been the construction manual for Rohn Towers. When I got my copy they were only a few dollars (not quite so cheap anymore). They are more of the safety/engineering 'point of view' so seem like they might be 'over-engineered' a bit. They are NOT over-engineered by any means!
Towers have a lot more force acting on them than most people ever know about (or believe, for that matter). The old, "This will work as good as doing it ~that~ way.", thingy is fine, IF you don't mind doing it again later, after repairing whatever the thing fell on. A small hole and a couple of bags of 'quick-crete' just won't 'do' it. It's like comparing the tower to a 'see-saw'. The force of the wind on one side, the weight of the concrete on the other. If the concrete side doesn't stay down all of the time, one of those 'times' when it doesn't means the tower will come down. It really isn't that simple but that'll give you the idea anyway. All tower manufacturors have minimum specifications. Find out what those are for your tower, and remember that those are the 'minimums', more is better.
Can't tell you exactly what you should do cuz I have no idea what your tower is, and my memory isn't very good anyway (loaned the @#$ 'Rohn' manual, haven't gotten it back yet). That's the best advice I can give...
