PING Sigma G D66 FAQ
Does the PING Sigma G D66 have a heavy or light head feel?+
The representative listed head weight is 350 g, which sits around the 26th percentile among PING putters with this field available. The head is lighter than most comparable PING putters here, producing a lighter overall head feel than modern heavy-head designs.
What putting stroke is the PING Sigma G D66 aimed at?+
PING lists the stroke fit as Slight Arc. Treat that as a starting point, not a rule. Aim, face rotation, impact pattern and visual preference still decide whether the putter actually fits you.
Is the PING Sigma G D66 putter unusually long or short?+
The representative listed length is 34 in, which sits around the 37th percentile among PING putters with this field available. This specification sits near the middle of comparable PING models in the dataset.
Should I choose the PING Sigma G D66 based on head weight?+
Not by itself. Head weight changes feel and tempo, but total weight, shaft, grip, balance, green speed and your stroke all interact. Use head weight as one fitting input, not the final answer.
How old is the PING Sigma G D66?+
The audited record places its launch around 2017. That makes it roughly 9 years old in 2026. Condition, shaft integrity and whether the club was altered since new can matter as much as the original spec sheet on an older club.
