[TowerTalk] Rohn 25 sidemount

I am in the planning stages of my first tower.  I am looking for some  
opinions on side-mounting a 24' boom 8.5 sq ft tribander (rotatable) on a Rohn  
25 tower.  Assuming that the tower windload is not exceeded (if all the  
load was at the top- which its not) does the rotating sidemount put  too much 
stress on Rohn 25?  I'm planning a 70' tower with guys at  35/70.  I'm 
planning on tribanders at 72/40.  I live in a  70mph zone.  What brand of 
sidemounts are you  using?  I havent considered ring rotors yet since they 
seem to be more  problematic but they would seem to put less (or more evenly 
distributed) force  on the tower legs. I dont see much available for Rohn 
25 which may be the  answer to my question on tower stress.  The only side 
mount I see  for 25 is from W9IIX which bolts to one leg.  Intuitively, this 
seems like  too much twisting stress.  What do you think?  
Thanks!  Steve WA3A
