The very first post shows two balls frozen together in the pocket without falling. Old Gold Crown pockets will let both balls fall into the pocket easily. So it has been shimmed or modified to tighten them up.
Incorrect. As I pointed out in a previous post, pocket size is measured at the mouth of the pocket (point to point) not at the throat. The table in question is not "tight". On most tables, two balls will not pass the throat of the pocket unless the pockets are 6"+ (at the mouth).
