Nike has a series of three VR irons: TW Forged, Split Cavity Forged, and Full Cavity. Tiger goes for the TW Forged of course, but mere mortals may prefer the Split Cavities, which have traditional looks, and a top line and sole only slightly thicker than the TW Forged, and they have a hint more offset. Designed to offer forgiveness while still aiding shot shaping, the Split Cavities are fitted with Dynamic Gold steel shafts.
