Forgiveness
Thanks to the isometric head, the hitting area is increased in size. You therefore benefit from a larger sweet spot. This not only reduces errors, but also increases the power of your shots.
Flexible shaft
A racket with a flexible shaft offers maximum power and makes up for technical errors, which allows you to send the shuttlecock back more easily when you are down.
On the other hand, a rigid shaft offers more responsiveness, precision and speed as it deforms far less during impacts (less catapult effect) and the shuttlecock therefore leaves the racket more quickly, but with less power.
