Here's what Kastaplast has to say - AHOY REKO LOVERS! THE X-VERSION HAS BEEN FREQUENTLY REQUESTED, AND IT’S NOW READY TO ADD THAT LITTLE EXTRA STABILITY TO YOUR GAME. THROW THIS WORKHORSE OFF TEE, ON APPROACHES OR PUTTS. The Reko X shares many shapes and dimensions with the classic Reko, with the concave wing as the most obvious exception. This feature allows a more distinct grip and makes the disc a better headwind fighter.
