I had them for a couple of months before H. I thought they showed a lot less chatter than expected when I got them considering that they're 2011. I think he would agree that they were in similar condition when he got them (that is to say...no chatter that is bothersome). Since then, he said he's been working on tight lies by hitting balls off his driveway, but who knows? :)
Here's a decent comparison: less chatter on these in September when he got them than I've had on super soft mizuno sets after 8-10 rounds.
