I've been wondering these 2 ways of swinging my racket. Ex. My stiff racket needs to bend to store energy. If it does not flex right, then I don't generate much power. 1. Left drawing shows the racket has already flexed from the initial swing and is recovering from the bend at the moment of impact. Racket is bouncing back to original shape while energy is released. 2. Right drawing shows the same racket is still being flexed(and moving fast) at the moment it hits the shuttle. People say tighten your grip until moment you almost hit the shuttle, but if I tighten too early it result in racket bending early and shaft is almost straight when hitting the shuttle(left). If I'm too late, the racket start to bend or bending at the moment of impact(right). Which drawing is correct to transfer more energy to the shuttle for clear & smash?
