What PING Says:
The winningest putter in golf history continues to set the standard with its rounded corners and soft ballasts, making setup and aiming easier in the slight arc design. Heel-toe perimeter weighting ensures forgiveness.

Features & Benefits:

• Quality and precision – A solid block of forged, 303 stainless steel requires more than four hours of milling time; precisely shaping every surface and radius
  to achieve the high quality and premium look expected in a precision-milled putter.
• Control and consistency – A precision-milled face pattern, known as deep AMP (Aggressive Milling Pattern), is inspired by tour player feedback and provides
  the feel and speed control you need to deliver score-lowering consistency on the green.
• Grips Galore – Your design wouldnt be complete without a painted-filled grip to further differentiate your putter from the rest. Blue, gold, green, orange,
  red, pink, yellow, purple, white and blackout are there for the choosing.
