CGC Forum linkExactly. To anyone who has taken the time to look...it's pretty obvious. I have something like 23 examples of the waviness problem here . You can tell by the newton rings on many of them "exactly" where the mylar is and is not touching the case (in the waviness at the top of the book). Just two examples: This one's a really big pic.

CGC Forum linkMy AnalysisI'll make this as short as possible, since I know most people don't appreciate long posts. This new case has three killer defects: 1) Newton Rings obscuring visibility 2) Damage from Accordion Effect (Waviness) 3) High-Pressure Holder Design The first two have been talked to death, so I won't go into them. And I won't address a fourth possibly fatal flaw at all since we don't have enough data yet - ink lift from high-pressure Mylar contact. But the third is actually my biggest concern because the damage is immediate. It is also currently the proximate cause of the first two. Remember those poly bags where the seam leaves an indentation down the entire book? Imagine the light forces involved in creating that defect. Now consider the considerable force necessary to prevent shaken comic syndrome (SCS) and book shift while in transit. I don't want to turn this thread into a pressing argument, but a qualified presser employs several techniques to avoid crushing the entire book while he removes pressable defects. A qualified presser can do this without stressing the staple areas or removing that beautiful spine bloom that everyone talks about. He can also take great care with older, slightly brittle books. By design, this new case cannot avoid those areas. Nor can it avoid the ledge formed by the undersized MicroChamber paper (MCP) inside the covers. As soon as the book is encapsulated, it experiences these forces across the entire book surface. And as we've seen from the Pressure Map, the highest forces are currently along the spine and opposing side of the book. There are ways to mitigate/eliminate the newton rings (coatings and roughened surfaces). There are also ways to mitigate/eliminate the Accordion Effect (pressure uniformity). But the design chosen cannot escape the High Pressure Holder problems, no matter how much tweaking is employed. Even with 100% pressure uniformity, the high points of the book will always experience the most pressure. This is a killer flaw in the design.
