I think bob's right that it's not a newton ring thing and if the collar has let loose somewhere that would explain why your rainbow colors look different than the other day.
Possibly. I'll check it when I get home tonight. But it went from having minimal newtons close to the edge, to the whole head having them. I think the bottom layer snapped out of the collar - it has that nice dead muted Evans hydraulic sound. Perhaps the Pinstripe solved that issue by using the pinstripe to adhere both layers together?
