WE BBs?

A new shop just opened up near me and I went to check it out. They have a lot of higher end stuff including their BB selection. The one that most interested me was that they actually carry WE BBs in all of the heavy weights from .28 - .43. The packaging said "5.95mm +/- 0.01mm".

I searched the forum and didn't actually find any reviews of these, so I was just wondering if anyone has experience with these ones. Thanks!
