[TowerTalk] torque arms or not?

[Roger (K8RI) on TT]

Although it's a common practice with hams, Guys should be attached to a 
bracket, not individual tower legs.
It's not normally a problem, but guy brackets like ROHN sells puts no 
strain on an individual tower leg.  On a heavily loaded tower,(near its 
wind load limit), when the guys are attached to individual tower legs,  
in high winds, the tower leg on the windward side takes the strain. With 
a guy bracket encircles the tower with the guy strain taken by the 
bracket and converted to a downward force, putting far less strain on 
the tower.

You don't see commercial towers with the guy wrapped around a leg.
