My hunting partner shoots a Razortec with the TR DZ,and he too,was concerned about the cord rubbing.The solution we came up with was to install a Bowtech cable slide with the string hole(2003 Bowtechs)and just put the TZ string though it,instead of serving it into the cable.You can also just drill a hole though a Simms or a Bowmar type slide.Works like a charm....Bob
