My last observation is most of the Player I see playing pool. HIT too HARD, a fault I too am trying to rid myself of.
I bought some pocket reducers for my pockets and I hit the balls half the speed I use to with way more accuracy. They actually make you concentrate on making the ball dead center. Frustrating some times when you think you hit a ball perfect and it pops out but I've seen an improvement in concentration and pocketing. Anybody that hits the ball too hard should get you a set of these. It will break you real quick. You will learn to give yourself the angle to roll balls in at pocket speed.
