The developed version of the original Head Lynx co-poly is called Head's Lynx Edge. This string tightly grips the ball with its seven sharp edges, enabling the player to make enormous turns. This co-poly provides better than anticipated comfort for a control string, much like the round version of Head Lynx. As a result, it is perfect for players who are driven or in the middle of the road and require a somewhat more forgiving off-kilter effect.
