I just checked a hand full of scrap nozzles and the scuffing is usually on the right or left of the needle. If you have the cross pin facing you and looking down on the nozzle most of the scuffing or wear was on the left side, sometimes on both sides

Grant- I'm not sure when it gets to the point when egos begin to over-ride productivity but at some point it does. I remember working at a large OEM builder of NIC cards back in the early 90's. We had a line manager for each line per shift, (5 line
