Harry and Everyone: Now that the USGA has their web reference up to note conformity to the new scoreline rule, there is bound to be some confusion. Everyone needs to keep in mind the fact that all EXISTING models of heads of 25* and higher loft do not have to conform to the new scoreline rule until Jan 1, 2011. Most of us have been starting the changeover of our existing models now so that we can have enough time to get them through what is a VERY difficult conformity process thanks to the incredibly small +/- tolerances for the new scoreline configuration. As a result, many, and I mean many, of the companies' models are getting an initial non conformity ruling from which they all have to then keep working with their foundries to get sets to the USGA which finally do make it through this incredibly tight inspection process. By incredibly tight tolerance, I mean that the top edge radius of just any two of the lines on any two heads in a set can be off by 0.001" and the whole set does not pass.
Previous to this new scoreline rule, the USGA only checked 3 heads from a full set of irons, now they are checking every line on every head in a set with scoreline tolerances which are much smaller than ever before. So many companies have had to remake sample numerous times before they get them approved. At the same time, this also means if it is that hard to make ONE set correctly, what do you think the odds are that every head of all the many production heads are going to be within the rules? Not much, I can assure you because the USGA really created a real nightmare for the club companies with this new rule.

My other son has KZG CB and they do not conform. Not that anyone of us is playing professional matches. Just nice to know if a set conforms or not. Now our Vokey wedges do not meet the 2010 groove rule, although the heads are about 5 years old (pre SM). ________________________________
