Boy you're not kidding about the muscles part!  My buddy has the aluminum 
spidermast, and although it is well made, it is beyond difficult to push up 
with even the lightweight spiderbeam on top.  If you have any kind of wind it 
adds  downforce on the mast in addition to the existing weight and friction 
between telescoping sections.  My buddy came up with a jack system to push the 
sections up mechanically, which helped a great deal, but added complexity and 
extra steps to the process.
