The titleist910 d3 driver are progressive and dynamic and designed to deliver a further,higher, straigher ball flight.The key to theRocketballz irons' distance performance is their large, thin clubface thatflexes like a trampoline thanks to a strong, stiff perimeter and a thin inneredge. The flexion in the clubface is further benefitted by TaylorMade'sInverted Cone Technology technology, which expands the portion of the face thatis designed to produce higher ball speeds, thereby promoting distance for shotshit off-center.titleist 910 d3 are built progressively throughout the set. From small, compactshort-irons, through deep undercut-cavity mid irons, and large hollow longirons, each iron is designed to promote the proper trajectory and distancegapping. The majority of the set features TaylorMade's Multi-functional Sole,while the sand, attack and lob wedges incorporate TaylorMade's new ATV sole.TaylorMade are using aurethane layer, developed in Japan,for the first time to absorb unwanted sound and vibrations. The new soft andpliable system is featured in all irons from 3 to pitching wedge, and dampensvobrations without slowing the clubface.
