Can anyone compare this racquet to the KFactor Six One 95 (18x20)? In terms of power, stiffness and swing weight? Are they similar at all? Or are they completely different? I've been using my KFactor for seven years and I might change my racquet to a newer one and the Yonex is on my mind.
You need to stay closed before you hit.
You open up too early and lose power and stability.
Follow through and service motion after your trophy pose looks ok.
More racquet drop would help your serve speed.
What you are lacking right now is the trophy pose.
You need to bend your legs, stay...
