What Mizuno Say:
A confidence inspiring hybrid – engineered to produce a higher, draw biased flight. The ST-X hybrids are suited for moderate swing speed players who need elevated launch to reach both their optimal distance and controlled landing angles.

Benefits:

• MAS1C Maraging Face - Delivers greater energy transfer and faster ball speeds across the clubface
  
• Quick Switch Adaptor - 4 degrees of loft adjustability to fine-tune look and trajectory
• Harmonic Impact Technology - Fine tuned head geometry delivers ideal impact feel and feedback
  
• X-Axis design for draw bias - Expanded toe located carbon composite window, with heel located sole weight combine to produce a reliable draw bias.
  
• 'Dense' or solid feedback - The majority of Mizuno's tour players expressed a preference for more dense feedback through impact. Mizuno's engineers spent a year finessing the sound to a more muted, powerful tone.
