There's no design problem with a Diamond table when it comes to losing the chalk in one of the tracks. The tracks are designed for BALLS that are round to roll down them, and Donny is right, the chalk will work it's way through the table and come out with the rest of the balls. If you want to see where your break cloth is at, look through were you place the rack. From there, you can see up the entire middle of the table
Tie a string around that break cloth, then let it hang over the edge of the rail, that way if someone drops it into a pocket,
the string will still be hanging out to grab
