Sigma 2 Tyne 4

The Sigma 2 Tyne 4 is a mallet-style putter in Ping's Sigma 2 line, built around a slant neck per golfaustralia.com.au's reporting, which also describes two fangs on the back of the head as a design feature. The maker's page, describing the grip fitted to the line, calls it a "straight-taper, midsized pistol with larger flat surfaces for increased face awareness," and notes the 17" grip is "heavier than a standard grip to act as a counterweight for more stability and control throughout the stroke." golfaustralia.com.au lists the grip on this release as the Ping PP60 Pistol.

Reviewer opinion on the Tyne 4 centers on how the slant neck's toe flow pairs with the forgiveness of the mallet head. One review credited to the site's own notes found the combination "matched stroke well" and said the head "framed the ball well at address," adding that it offered better alignment than the Anser. golfaustralia.com.au went further in its own testing among Sigma 2 models, calling the Tyne 4 "surprisingly my favourite of the three."

Within the Sigma 2 line, the Tyne 4 sits as the mallet option built around toe flow rather than a face-balanced or blade profile, and the record so far shows two independent reads landing in its favor, one on stroke fit and alignment, the other on overall preference against its siblings in the family.
