The flex-first refuge. Thin, very soft box beams skinned in TeXtreme × Twaron spread-tow carbon-aramid, and on some molds O3 — string-sized ports instead of grommet holes, a genuinely different aerodynamic and feel (and the loudest whoosh in tennis). RA numbers the big brands abandoned decades ago.

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.
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.
