As I promised before, I am going to write on things you must know about long pimple rubbers. This report is a result of my little research which I carried out into long pimple rubbers. I have looked at many sources on long pimple rubbers and I am just trying here to present my information in a simplified manner.
All pimple rubbers have less grip than normal smooth rubbers. Most of long pimple rubbers have rough pimples that grip the ball, while some LP rubbers have smooth and grassy tops that do not grip the ball. The sides of the pimples vary in the same way producing similar effects in their grip of the ball.
The ability of pimples to bend when the ball is hit depends on their softness. The softer the pimples, the more they bend.The ability of the side of the pimples to touch the ball and affect it is based on the softness and the flexibilty of the pimples. This is why a soft and flexible pimples produce more spin variation than stiff pimples.
The width, density and the shape of the pimples are also important. The wider the pimples, the less they bend, so their sides have a less abilty to touch the ball and affect it.The more dense the pimples, the greater contact is made with the ball affecting more the spin on the ball.
The thickness and hardness of the sponge of LP rubbers are important too. The thicker and softer the sponge,the more the pimples sink into the sponge when the ball is hit.The pimples now have a greater ability to touch the ball and generate spin. The thicker and softer sponge also catapults the ball back adding some speed. LP rubbers without sponge do not have this effect and they are quite slow.
According to the the general principle about rubbers, when one spins the ball and the opponent does not change its spin, the ball will keep spinning in the same direction (the overall motion will be in the other direction).So, if you hit a topspin stroke, you will receive a backspin ball. Your backspin stroke will come back to you as a topspin shot. This is easier to do with long pimple rubbers than smooth rubbers.Apart from this, LP rubbers can kill, dramatically increase and reverse the spin on the ball.
Imagine you hit a topspin stroke and the LP player hits it back with a flat, non-brushing stroke. The pimples will bend in many directions and grip the ball as they spring back quickly into their position. This process will kill the spin on the ball. Therefore, the ball will come back to you with float or a lttle backspin.When the LP player hits the ball with a backspin style shot with a flat non-brushing contact, he will also kill the spin on the ball.The pimples bend all directions gripping the ball in a pincer-like effect before they spring back to their position. So, the ball will come back to you with little or no backspin.
When you hit a ball with heavy backspin, the LP player can also kill the spin. What he should do is to hit the ball flat without any brushing.The pimples will bend in all directions gripping the ball in a pincer-like effect before they rebounding into their position.The ball will come back to you with little or no topspin.When the LP player offers a backspin style shot with flat, no-brushing contact, the pimples bend in many directions and grip the ball quickly. They will kill the spin as they spring back to their position. The ball come back to you with float or a little topspin.
LP players, as explained above, will return most of balls as dead balls by eliminating the spin on the ball. When you play against these players, you might feel that the ball sometimes wobble. The general theory is that the spin on the ball will keep the natural path of the ball. The topspin ball tends to drop towards the table , while the backspin ball tends to rise.The sidespin ball curls in the direction of the spin. Thus the spin prevents the ball being affected by the air currents moving around the playing area.If there is little or no spin on the ball, the air currents affect the natural path of the ball. Air currents work with the gravity to force the ball to go down, while currents moving upwards or sideways will make the ball move up and sideways.So, the LP players can make the wobbling process really happen by killing the spin on the ball.
To increase the spin on the ball, the LP player will resort to a particular stroke. Imagine that you hit a topspin shot against a LP player.If the LP player wants to increase the spin, he will hit the ball with a backspin style stroke with heavy brushing The pimples now bend in the same direction(the opposite to the direction the bat is moving).So, when the pimples spring back to their position, they will increase the spin on the ball.The ball will come back to you with heavy backspin.Now imagine that you hit a ball with heavy backspin. The LP player can offer a topspin style stroke with heavy brushing the ball. The pimples will bend in the same direction and as they spring back to the their position, they will increase the spin.The ball will come back to you as a heavy topspin ball.
The above description should show that the LP players can reverse the spin on the ball than the players who use normal rubbers.They can reverse a heavy topspin shot to a heavy backspin return by offering a backspin style stroke with heavy brushing the ball. They can reverse a heavy backspin stroke to a heavy topspin shot by playing a topspin style shot with heavy brushing the ball.
