Stringing information for :

Offering an ideal blend of power and control for the intermediate through advanced player, the Biomimetic 400 is an appealing choice for a variety of playing styles. With a more solid feel than the 500 range, this one still feels easy to maneuver. Easy acceleration through the hitting zone makes both pace and spin effortless to develop. The level of comfort from all areas of the court impressed our TW playtesters. At net the racquet feels crisp and precise. Targeting is spot on both when punching volleys deep as well as when caressing the ball with touch. As from the baseline, power and spin is also easily generated on serve. Perfectly filling the gap between the control oriented 300s and light, more powerful 500s, this 400 blends elements of both and impresses greatly.
