I'm glad I found this old thread. Today I played a good stretch of maybe 3 hours on my recently setup table for the first time, and I don't think I ran more than 20 balls. My pockets are 4.25" corners and 5" sides, and I got a ton of rattles. The facings are also very hard, and I don't know whether that contributes to rattles. But this thread makes me feel a little better about my play today. Man, this table is turning into such a headache and money pit for me. Along with looking to replace the warped slate, at some point soon I really have to have the rails redone to open the pockets back up to a reasonable opening, so I can enjoy the game.
