David Jones, Senior Design Engineer: "Fitting for weight in putters has been largely unexplored beyond the Tour level. Now, we want to give amateur golfers the ability to change putter feel before a round. We include 20- and 28-gram options in the weight kit because they represent the most noticeable feel differences."

How it works: The iconic head style, made of stainless steel, has a two-piece face insert (stainless steel and elastomer) and interchangeable weight inserts ("iWi") along the sole. Combining a steel face with soft rubber backing delivers a steel-like click, plenty of feedback and repeatable distance output. Two 12-gram removable plugs contribute to a head-heavy sensation and rhythmic, controlled stroke. (The weight kit is sold separately for $70.) Use the additional plugs to tweak head mass—and feel—to your stroke or green conditions.
