iWi D66

The 2009 iWi D66 is one of six head shapes in Ping's iWi line, a lineup that putterzone.com describes as including Anser and Zing shapes among its six models. The D66 sits toward the mid-hang, arcing-stroke end of that spread, a fit checkyourgolf.com calls a mid-hang model designed for use with a slightly arcing putting stroke.

The record here comes entirely from editorial reporting, none of it verified independently. Putterzone.com describes the face as cast from 17-4 stainless steel with a 304 stainless steel insert encased in elastomer, a two-piece construction meant to deliver steel-face performance with a softer feel. That same outlet lists the head weight at 345 grams, an MSRP of $169 USD, and a weighting system of 12-gram removable steel weights in the heel and toe, with an optional kit of 20-gram and 28-gram tungsten weights, priced separately at $69, allowing for nine possible weight combinations. Putterzone.com also notes Hunter Mahan playing the D66 at the Ryder Cup, and describes the insert's natural silver tone set against a darker head shade, with a yellow accent carried across the sole, grip, and headcover.

Opinion on the D66 splits in a familiar way. It's praised for a clean, classy look at address and a rock solid feel, with putterzone.com summing it up as playing like it looks: rock solid, offering a compelling union of high technology and sturdy playability. Other commentary agrees on the firm, bass-note feel in the sweet spot but flags early trouble finding that sweet spot consistently, describing heel-blocked putts before the stroke settled in. The yellow accent color draws some pushback as well, and the $69 weight kit is called a bit over the top on price, even as the underlying design earns the "rock solid" label from more than one corner.
