前に使ったことのあるブランド、YES!のパター。
ピン型だと、なんかフェースが開いてしまう気がするんだけど、これはシャフトのつき方が他のと違うので、弧を描いて打つ必要がなく、ただ真っ直ぐ後ろにひいて、真っ直ぐ前に出せばいいらしい。
そういう技術をあまり必要としないのがいいわ（＾＾）ということで、使うことにしてみた。

Featured Technologies
C-Grooves 2.0
Every face is perfect because it's 100% precision CNC milled with no inconsistencies and the highest tolerances. The 20-degree upward cut of the C-Groove's concentric edges grip the ball's surface and apply physical forces that simultaneously lift the ball out of its resting position. Yes! putters achieve forward roll 21.5% quicker than other putters which repeatedly skid, skip and spin before settling into forward roll.
True-Square Alignment System
The TPU insert, cavity alignment line and center of the C-Grooves on the face align perfectly together on a single plane. This helps you frame the ball closer to its center of gravity location. Whether you are left or right eye dominant, True-Square helps you square the putter to the ball with the alignment lines on the topline and cavity.

Adams Yes! Tracy-12 Putter Details
The Yes! Tracy Putter from Adams Golf features a heel-toe cavity back design offering a precision milled face with the legendary Yes! C-Groove technology. Having been used to win two US Opens, the Tracy has a Tour-proven record of making putts, and making them when it really counts.
Every Tracy has a perfect face because it's 100% precision CNC milled with no inconsistencies and tested to the highest tolerances. C-Grooves act to grip the ball's surface, while simultaneously lifting it from its resting position to achieve forward roll 21.5% quicker than other putters. Quicker forward roll means less skid, skip and spin, and that means truer rolls every time.
The Vibration Dampening insert located in the precision-milled "through slot" located behind the putter's face is made of thermoplastic polyurethane (TPU 65D) that captures vibration for enhanced feel and responsiveness. True Square Alignment helps you frame the ball closer to the Tracy's center of gravity location and square the putter to the ball so your putts start on your intended line.
