It is my opinion, based on 40 yrs of experience, that the torque  bars do 
improve tower stability. This is noticed if you are up the tower when  
turning a 
beam.

    Actually that's sort of right. Rohn made those torque arms for years and 
hams used them since it sounds logical. When Rohn implemented one of the early 
EIA/TIA-222 tower standards, they found that the torque arms added nothing to 
the torque resistance of the tower but they do help stabilize the tower as 
it's being climbed. 

    Based on this Rohn quit making them but acquiesced to ham demand some 
years later - "I've always used them so they must be necessary" - and started 
making them again. 

    And trying to force a thimble in those little holes isn't necessary, just 
use a clevis/shackle as has already been pointed out. 

Cheers,
