String & Racket Finder
WILSON CLASH tennis rackets compared
The rare case where the gimmick is real and measurable. FreeFlex is a carbon mapping that lets the frame bend in planes rackets normally refuse; StableSmart is the geometry that keeps it from twisting anyway. Result: stiffness numbers in the 50s with normal stability — genuinely new when it shipped, still the arm-friendly modern benchmark.

Swipe the table sideways for the remaining columns.
Axes, in order: Control (flat) · Precision · Spin · Power · Feel / comfort · Stability · Maneuverability · Serve · Smash & overhead · Slice / touch · Return / blocking. Difficulty is how demanding the frame is to use well, not how good it is.
Choosing between them
Frames in one family share a construction story but not a playing character — head size, pattern and swingweight move the numbers above far more than the marketing does. If you want a shortlist matched to how you actually play, and a string bed matched to the frame, the finder does that in a few taps.
