Ping Ally Blue Onset Putter Review: A Foolproof Solution For A Certain Miss

While adoption on tour of the Ping Ally Blue Onset putter hasn’t exactly been widespread, it has generated significant buzz thanks to it being the catalyst to a stark turnaround in form of Wyndham Clark, who since making the switch has notched up a US Open win and two other PGA Tour titles, albeit with the counterbalanced version.

Intrigued by the performance claims and validation at the highest level, I decided to put this putter through its paces over the last few weeks to see if it lived up to the hype and can be labelled as one of the best putters on the market.

The first thing that hits you at address is the stark white finish. It creates a bold contrast against the turf, making the alignment system pop. This form what Ping is calling its Eye Q technology, an alignment aid that uses a top-rail black dot to stabilize visual focus. This design is said to help calm the mind, quiet the hands, and significantly increases ‘Quiet Eye’ duration, resulting in a steadier, more assured putting stroke during high-pressure moments.

Regardless, the combination of the long, clear sightline and the single top dot provides remarkably vivid visual cues. Setting the face square to your intended target line feels easier and almost automatic, helped by the fact the putter sits exceptionally flush to the green and very neutrally.

However, the bright white finish does come with a minor caveat in direct sunlight. On bright days, shadows cast across the white head from the shaft tend to stand out much more noticeably than they would on a traditional dark or anodized finish, which can be slightly distracting when it occurs and makes the alignment system less powerful.

During testing, the most immediate performance characteristic was a distinct right-side bias for me as a golfer that tends to aim right and pull putts online. For golfers who struggle with pulling putts or missing left, this putter is an absolute asset.

While it requires a brief adjustment period to dial in your aiming visuals and learn where to point the face to hit your intended line, it rewards you once calibrated. For my set up faults, the right bias tendency combined with the onset shaft design naturally neutralized my stroke.

The onset construction noticeably smoothed out my putting arc, taking out variables and encouraging more of a straight-back, straight-through motion. The onset geometry places the shaft axis in front of the putter's center of gravity, meaning the club is pulled rather than pushed through the stroke. This pulling dynamic delivers exceptional stability and the forgiveness of a mallet while preserving feel. 

Despite its high-MOI mallet performance, the Ally Blue Onset is surprisingly compact. It avoids the bulky "frying pan" footprint common in modern high-stability putters, maintaining a sleek, manageable profile at address, albeit in a rectangular profile that perhaps not everyone will appreciate.

In spite of the scaled-down head size, forgiveness is impressive - one of the most forgiving putters I've tried in recent years. Off-center hits maintain speed remarkably well, making long-range distance control a standout strength. While the impact of Ping's Eye Q technology is almost impossible to measure, my real-world testing showed consistent ball speeds and reliable start lines across the face once the right bias was accounted for.

Ping has struck a pleasant balance with the impact experience too. The feel off the face lands in the sweet spot - soft and responsive, yet far from mushy. There is a clear, audible "click" at impact that provides immediate sensory feedback on your strike quality.

This acoustic feedback translates directly into confident speed control, giving you a firm sense of energy transfer without sacrificing soft touch on delicate downhillers.

The stock SuperStroke Pistol 2.0 grip is comfortable and helps with both feel and distance control.

The Ping Ally Blue Onset putter is undoubtedly one of the most effective mallet putters on the market. Inconsistent golfers typically struggle with speed control and aim, and this putter provides a solution that every level of player can benefit from.
