Finding a suitable blade is not easy. Should it be an allround blade or the enormously fast carbon trowel? The most important thing is to be honest with yourself. It doesn’t make sense to buy the newest, fastest and most expensive blade if you can hardly play a backspin safely over the net or if the technique is not yet fully developed.
The best thing is to find a compromise between what I want to play and what I can play. A youth player, who is able to play a safe topspin and has been playing an allround blade, which he got at the beginning of his TT career, should, if he now wants to have faster material, make a small step at once. For example looking for a blade with OFF- or instead choosing at first a faster rubber on the current blade.
The change of a blade should be well considered in any case. Your first step can be the racket of a fellow club member, whose equipment can be tested. In addition, there are many local TT stores where you can get test sets, which makes testing easier. Much more attention than on the attributes within the product descriptions should be devoted to the structure of the individual blade. Elastic 5-ply allwood blades without a fiber such as carbon support the spin game and are generally more controlled and softer to play.
For higher training effort and stroking power, 7-ply solid blades or those with fiber-layer reinforcements should be considered. These are stiffer and often much more direct. The speed reserves are significantly increased, but it is more difficult to control such blade due to the lack of flexibility. Ultimately, it is also a matter of feeling, with which table tennis blade you feel comfortable.
The most important hint for the choice of your blade: Once a suitable blade is found, then it should be kept.
