Presenting REXIS SPEED! Our test results place it at the soft end of the spectrum, despite Yonex's design for it to be the firmest member of the Rexis family. REXIS SPEED has exceptional pocketing, above-average control for a soft string, and a comfortable, muted feel at impact thanks to its army of nylon and polyester filaments. When strung tighter for control, this string maintains its comfort, feel, and touch while still providing an arm-friendly hitting experience. It will also give any hybrid a bit more power, comfort, and feel.
