No question -- use a dedicated twisted pair for every circuit that 
you want to control. Shielding is FAR less important than twisting. 
Bond one of the conductors to ground at the sending end. This 
provides the best noise immunity by far (and probably the least 
problem with lightning) because it minimizes the loop area.
