[TowerTalk] Pier pin on Rotating Tower

[john at kk9a.com]

If you are rotating the entire tower you would have a tower bearing at the 
base and the structure below the bearing would be in concrete.  If you are 
rotating only the upper part of the tower, then you could use a pier pin 
base.

I am planning a rotating 55G tower.  Understanding the current
preference to place a guyed tower on a pier pin baseplate, is this still
true for rotating the tower?
Thanks for input.
