Nick, I think the major flaw in the design of all pool tables starts the moment the slates are attached permanently to the frame, and by that I mean, the table has to be taken apart in order to corrective level the slates in order to compensate for the movement of the frame, no matter what table it is. No leveling system will work 100% if the slate is mounted to the frame in a way that the attachment points can't be reached in order to offer the slates some kind of relief at that point, which is the reason why pool tables have to be taken apart in order to level the slates, and in most pool rooms, the installers don't want to take the extra time needed to open that can of worms, having to deal with the slate seams every time they install new cloth.
