String & Racket Finder
TECNIFIBRE T-FIGHT tennis rackets compared
Medvedev's actual frame family. Isoflex varies stiffness around the hoop so the response map is even instead of sweetspot-or-nothing; Foam Inside and the RS Section do the solidity. One of the few tech sheets where each name maps to a design decision you can feel.

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.
