Yes C-Groove Putters (general range)

The Yes C-Groove line ran, according to best-putter.com's reporting, from 2000 to 2012, built around the C-Groove face milling the publication describes as C shaped grooves cut into the putter face, with slanted edges tilted down towards the ground. Best-putter.com also credits the design to Harold Swash and reports that only Yes have the right to manufacture putters with this groove, though these are the publication's figures, not verified claims from the maker.

Best-putter.com's own assessment of the range is mixed, praising the roll off the face while conceding "Absolutely, except for the fact that until recently Yes Putter designs have been ugggggly!" That tension runs through the wider Community reaction as well: putters in the line are said, in opinion, to roll extremely true and further than expected, a sign of a well-struck putt, with a quieter sound off the face, while critics call the designs ugly, pointing to squared edges and sharp angles as not things of great beauty.

Best-putter.com also reports that almost the entire range is face-balanced, which the Community has flagged as a limitation, opinion holding that a face-balanced build across nearly the whole line makes it unsuitable for non straight-back-and-through strokes. Taken together, the record on this release is really a record of the C-Groove technology itself, the milling and the balance profile, more than any single head shape, with the reviews split sharply between what the face does to the ball and what the putter looks like doing it.
