I had a John Wall HRX that kept separating, they replaced it with a better one but it took a few months and I was up their a$$! I just pulled a Kenneth Faried Auto Prizm parallel and the prizm part has some minor defects that I am thinbking about havign themk replace, but especially with an auto, this could take forever and its such a nice hit with the way "the Manimal" has been playing i don't want to take the risk of them sendign a replacement card of someone worse. So my opinion is, think before you act, but non-autos shouldn't be a problem.
If you yourself aren't graded higher than a BGS 7, I don't want you pm'ing me!
