Hi Bernie, I agree with Doug but i strive to understand it, NBP-COG makes sense to me and I am going to try it out on a set I am putting together this week. I am still not sure about NBP, I am assuming that the spine is the section of the shaft that rolls away from the bend when a load is put on it from my spine finder, then the natural bend point will be 180 degrees out from that point? Then when you put the shaft into the housel and lay it off the end of the table the spine will point up and the NBP will point down towards the COG of the head? Does this sound right?
