Because only practice will make you better. The Rempe Training ball has two patterns one for beginners and the other for advanced players. The patterns help you see where to hit the cue ball for English. It will help you to develop a better stroke by teaching you a more accurate delivery of your cue stick to the cue ball and it will help you to optimize the rebound angle on ball and cushion for a better position on the next shot. Each Rempe ball kit includes a Belgian Aramith Cue ball with two patterns and a pocket size manual which will clearly show you how you can use the training ball to fully control a cue ball. Instuctions are included in English, Spanish and French.
