Yea thats what I am trying to say most one cams have one string all the way around the idler wheel back to the cam again. Mine has a dual track idler wheel. It goes from the cam up to the half way around the idler wheel, then another string starts, and goes back down to the cam. Those would both be considered the string wouldn't they? I mean if you twist a regular idler wheel bow it is the whole string, if you twist a dual track idler wheel bow it would have to be both strings to be equal. Is that right?
