     This is one of my favorite questions to answer on TT.  The best 
compilation of tower-related practice was created by N1LO: .  Steve K7LXC also recently published 
a book on tower practices.  Check out his web pages: .

     As for other self-supporting towers to consider, take a look at the 
Trylon Titan series.  You can find a full description on Steve's site.  I 
built (literally from the ground up) a T-500 in 2001.  The max height 
available with this model is 72 feet.  It's a true medium-duty tower; I 
suggest you check out the full loading capability of whatever tower you 
select vs the antenna loads you intend to install on it.  You can also 
select Trylon's T-600 series - it's a bit beefier but the maximum height is 
64 feet (one section less than the T-500 series.)

     Pouring all the concrete at one time is a good idea.  The mixer truck 
will mess up your yard only once.
