Tin-aluminum bearings also don't show the same signs of premature wear in Blackstone oil analysis due to lack of lead and copper."

Even though 2010.5 and up have harder bearings, that doesn't fix the clearance issue, which is the main problem. I have a 2011 and I'm going to get the bearings replaced with BE bearings this week.
What a lovely position to be in when what ever you write about competition is taken as fact by the audience. Amen.
