From Sports Illustrated Golf+ Equipment Issue (February 8, 2010)
The set consists of hybrids (three through five), mid-hybrids (six and seven) and wide-soled short irons (eight through pitching wedge). Patented gapping technology ensures consistent distances throughout the set.
The six- and seven-mid-hybrids feature a four-way cambered sole and an H-back channel-vibration dampening system.
The short irons have low and deep centers of gravity, quad cavity backs and perimeter weighting.
