Typical House Shot aka THS

Typical House Shot or THS These patterns are designed to steer the ball toward the pocket. This is accomplished by applying a high concentration of oil in the middle part of the lane and leaving the outside boards extremely dry, creating very little, if any, “out of bounds.” The oil ratio on recreational patterns is in excess of 10 to 1. These patterns are also known as “typical house patterns.” .
