Our moderator has spoken before about an additional element you must consider regarding long masts... it is the dreaded:

Pucker Factor

This is when you are at the top of the tower juggling a behemoth mast and it decides it wants to go in a direction other than the one you are desirous of it attaining.

It is at this moment that your mind immediately recollects your high school physics class and the wisdom of Archimedes...

As that weight's force vector takes on more of sideways component you atop the tower tend to understand just what the

Pucker Factor

Is all about...

From the Unabashed Plug department, the upcoming issue of the PVRC Newsletter will include an article by K4ZA describing a uniquely clever solution to reducing the pucker when doing this job. It will be available February 1 on the web site at -- scroll down to the "News" section for the link.
