As I'm trying different racquets I noticed how swing weight influences the way I'm trying to swing my racquet. I mean if I distinctly perceive weight of the racquet head, which is most pronounced in Wilson Six.One 90, I'm cautious to take longer and smoother swing path, otherwise I feel like I will break my arm or something. Prestige Mid, even though its static weight and balance is about the same, does not swing as heavy, which "helps" me to get more "creative" with my strokes. Even more "lightheaded" racquets tend to get totally out of control and it hurts not only my stroke production but my arm as well. Now I'm thinking, as I'm watching Federer gliding through the air with his "cumbersome" racquet: maybe the secret of stability and consistency of top players strokes is in many ways defined by 360+ swingweight which smoothes out their swing path and forces good habits in stroke mechanics? I know it can be frustrating if heavy racquet does not arrive on time due to lazy preparation and footwork, but I remember it felt really good when I played a practice match with KPS 88, even though I was so tired I could not lift my hand. I literally had to dance around this racquet, to make it going through the ball, but it was so much fun! :shock: I know it's nothing new, but I finally realized that I need stability and fluidity/calmness in my game more than opportunity of being wild and do crazy (or lazy?) things sometimes. I guess I'm just getting older... or mature as a player :-?
