The Dunlop Biomimetic M4.0 is best suited to intermediate players with moderate swing styles. The racket is packed with many innovative technologies that provide high levels of power & control. It weighs 295g (10.4oz) & is made from a combination of premium graphite & Biofibre that is stronger than steel & lighter than carbon, which results in a cleaner, more solid hit. The M4.0 has a 100in 2 (645cm 2) head with an open 16x 19 string pattern & an enlarged sweet spot guaranteed by the Tru Oval shape that makes it more forgiving as well as provides extra power & more access to spin.
