The NGC copper coin Guarantee

I guess it has been a month since NGC has started to guarantee copper.Let's get some feedback.In your opinion; are the graders at which service more consistent,more correct and does it matter in which holder your copper coins are kept NGC,PCGS or ICG????

The mint state IH cent collections I've seen over the past year were mostly PCGS slabs, and even the top ranked NGC registry set is 2 to 1 PCGS. The biggest issue IH collectors seem to have with PCGS is with their NGC crossovers. So I get the feeling many of the nicest NGC IHs have found their way into PCGS slabs through the years. PCGS's guaranty may have been part of the reason but they've also been much more consistent with this series and earned their market value.
If PCGS changed their standards and changed there slab inserts to pink, there would be some type of migration or swing in the value placed on coins graded in different slabs.
Anybody make a claim yet?

Paul- The trouble with instituting a new standard and with it a new grading guarantee is that how does that bode well with the tens of thousands of copper coins they have put in holders in the past that will now not make their new tighter standards? The coins graded prior to the new standard will become worthless and how does that make NGC look when people complain of purchasing coins for thousands of dollars that are now worth hundreds? Makes me want to think long and hard before purchasing any of their coins as how do I know that they will not make a change in some other series? Changing standards is not good business. People come to expect certain standards and changing them will cast doubt on their whole line of product.
