Brand Blurb: The Dunlop Biomimetic M4.0 Tennis Racquet is constructed with AeroSkin CX and MOFS Grommet technology for powerful performance with total control over your swing. The TruOval head shape has an enlarged sweet spot and BioFibre technology for control and stability. Dominika Cibulkova and Nicolas Almagro both use the Biomimetic M4.0 to get that perfect blend of power and control.
Quick Take: With a little more mass in the head than the Biomimetic 400, our testers found the Biomimetic M4.0 to be slightly more stable with a lively spin-friendly response. The “M” in the M4.0 stands for medium swing speed, which suited our testers perfectly. It has a fast feel and nice maneuverability at the net. Dominika Cibulkova swung the Biomimetic M4.0 at the Australian Open and advanced to the finals. It's definitely worth a demo.
