TaylorMade Burner Individual Iron with Steel Shaft Every element of the TaylorMade Burner Irons is engineered to work with the next to promote more speed and more distance. The 2009 Burner irons offer longer and more consistent distance in every iron with more distinct distance-gaps between long- and middle-irons. The long-, middle- and short-irons were separately engineered so you get long and forgiving long-irons, long and accurate middle-irons and accurate and responsive short-irons. Inverted Cone Technology offers an extra-large sweet spot for added forgiveness on off-center hits for greater distance consistency from shot to shot. A multi-functional sole creates a low CG (center of gravity) position while reducing turf-drag and promoting the exceptional playability of a thin sole while the multi-material cavity badge dampens vibration and sound to promote extraordinary feel.
