From what I understand about the ticking problem was that when they, SLP, use to coat the DP and the FLEX with the Ceramic coating, that is what supposidly was causing the ticking. Since then, if you look at the newer copies of the SLP, the Flex and DP are no longer coated in the Ceramic coating.

Of course I have no definitive proof of this, but this is what I was told by several people I trust. Just thought I would pass that along here
