The Columbia ABC Masters Yellow Dot was urethane, maybe it is one of those? In any event, the best thing to do is continue to work on your form and timing since you are a new bowler. Once you are more comfortable and consistent with form and timing, then look into getting another ball for longer patterns. Your Pro Shop Operator might even have some used/plugged equipment they could redrill to your specs and sell to you at a discount that would work while you are still learning. Then, once you are truly comfortable with your game you can focus on buying brand new equipment. Just my $.02
