That's assuming the guys are hooked to a "guy bracket" such as the 
GA25GD for the 25G or the equivalent for the 45G which takes the side 
load off the tower legs and assuming the extra distance is "reasonable", 
particularly when using a heavy guy made of EHS. Also the longer the guy 
the more prone to low frequency oscillation, or galloping.
