Velocity Slots in the crown and sole of the club. Multi-material construction featuring tungsten heel/toe perimeter weighting in the long irons provides optimal CG location for increased forgiveness & higher launch * A channel that is literally cut through the head of the club from the top slot to the bottom, allowing for even more face deflection * A TPU insert which improves the feel of the club and give the hybrid a very crisp sound similar to that of an iron * Designers are able to optimize Velocity Slot Technology by isolating each slot shaping parameter, including the thru-slots, resulting in maximized CT * An increase in CT of 67%, levels only seen before in today"s titanium drivers
