i have a youtek radical pro, and would like to customize it, but am not sure how i would accomplish what i want, or if it is possible to accomplish it. here are the specs for the racquet. Head Size: 100 sq. in. / 645 sq. cm. Length: 27 inches / 69 cm Strung Weight: 11.6oz / 329g Balance: 2pts Head Light Swingweight: 345 Stiffness: 58 the things i want: i think the swing-weight is fine, but i would like to make it 1 or 2 more pts head light and i would like the sweet spot higher on the bed. it is also pretty flexy, so i would like it to be stiffer, or more torsional stability. also, would i benefit from having the strung weight higher? can i make the swing weight lower? i am not sure how to go about this process. i would also want the swing-weight to stay as low as possible. thanks.
