Len, your right about this type dialogue. I love it. I appreciate all the input from the techies who visit and share there experties here. The thread Pinwheel was refering too was a great exchange. I still haven' t concluded my test results of the two different schools of tuning yet. But I' m leaning towards a comb of both with an initial start with a bare shaft for spine and nocking point. To a seperate tuning process for F/P and B/H. I do have a compulsive obcession for tuning that I refer to as meticulous to satisfy my addiction. lol. I wish there was one tape or book that would cover all the different tuning processes, timing, string and cable work for duel cams, and the little techie tricks you guys have. Anyone have any references? Thanks. JERRY
