World Nineball Tour (WNT) uses heavily strict tournament specifications with tight corner pocket mouths cut down to roughly
4 inches (and 4.5-inch side pockets). To accommodate these ultra-tight openings without causing excessive ball rattling, the horizontal cushion facing cut angles are typically adjusted flatter/straighter (closer to 136°–138°) compared to standard recreational 142° angles, paired with a deep shelf.
