Playing on Boingy Rails
One day your pool playing abilities will take you away from your own table. You will be removed from your comfort zone and you will realize not every table is made the same. Some are different sizes and some have dirty worn down felt. You will have to be a dynamic player. If you are doing trick shots or playing a tournament, the elasticity of the rails is going to make a difference in the game. This is why you are going to need to learn to adjust for “boingy” rails.
Generally in humid conditions rails will be slightly more stiff. Moisture affects the materials inside the rails. So conversely in dry conditions you may run into super reactive or “boingy” rails. In either case you are going to have to adjust the line and angle of your shot. With stiff rails you can just put a bit more power behind your stroke, so long as you are capable of maintaining accuracy this will be fine. However, with boingy rails it is bit trickier. You do not want to run the risk of putting to much power into it, but you do not want to go to soft either. So instead of trying to hit the ball softer, just shorten the back swing of your strike. This will allow you to maintain the same rhythm and will slightly decrease the power, but not too much.
Try this shot out to see if the rail is extra bouncy or extra stiff. If you make it right in the pocket there will be no adjustment necessary. Line the shot from the corner pocket tot he sixth diamond on. Hit it with a half left english, as seen in the illustration to the left. If the ball hits the long rail it is running short and angles will have to be made a bit wider during your game. If the ball hits the short rail then it is running long and angles will have to be made tighter during the game.
Here is Dean for you. He is going to give you a little more information on how to use rails while playing. Just remember some of this stuff takes a little while to learn. So if you are not doing it very first try do not get frustrated or give up. You have to learn to visualize and then you have to develop the muscle memory, it takes a little bit of time.
