No, one cams are considered one string right all the way around the idler wheel back down to the cam again. Well mine is the hoyt versa cam with dual track idler wheel. so there is two strings connected to the idler wheel. I was figureing since my bow is a single cam, that those two string would basically be the one stringthat is on a single track idler wheel. Is that right? I didn't mess with the harness att all.
