helping me said absolutely nothing about plumbing the  tower with any kind 
of instrument.  When it was up and all three guy  sets were installed, one 
guy stood at the base looking up the tower while  3 others adjusted the 
turnbuckles at the guy anchors to get it  approximately straight and 
vertical.  Once it looked OK, each one  tightened his turnbuckle by the same 
number of turns until the guy tension  (measured with a Loos Gauge) was 
correct.

    Well, the vertical tolerance spec per the  TIA-222 is 3" per hundred 
feet. Some people are just more particular than  others.
