At PingSkills we have been asked how do you choose a good ball. It can be quite difficult if you are not sure what you are looking for.
The things to look for are firstly that the ball does not have a seam around the middle
of it that is visible. If you can see that seam you can reject that ball straight away.
That ball will often have a flat spot around the seam area. The other thing to look for
is how firm the ball is. This ball here you can see that when I press in reasonably firmly the ball caves in on the side. Whereas with this trainer ball you can see that the same amount of pressure and the ball does not budge. That is what you are looking for in the firmness of the ball. And this three star ball again you can put quite a lot of pressure and the
ball will not cave in. How much pressure do you put on a ball? If you grap your thumb
and push quite firmly so that you are going in to the bone, that is the amount of pressure
that you are looking for, for the ball to withstand. The another thing to look for is how round
the ball is. Now by just taking a ball like that it is often quite difficult to see that
it is perfectly round. The best way to do it is to spin the ball. By looking at it from
the top you can see if it has any wobbles in it. Think about spinning an egg and you
can see the egg wobbles quite a lot. Whereas with a perfectly round ball you won’t see
any wobbling from the top.
