Silver Swan putters from John Letters

The new Silver swan Range

John Letters has released three new putters in its famous Silver Swan range, all costing £49.

The SS1 uses the Classic 'anser' style heel and toe weighted design while the SS2 has a 'half-moon' head shape

The Silver Swan SS3 has been crafted with a traditional blade appearance for a clean, simple and uncomplicated look.

The extended flange flows off the back of the clubhead to re-distribute weight away from the face to create a larger sweetspot and more accuracy thanks to a clubhead more resistant to twisting at impact.

Its insert is milled to deliver a softer feel and more consistent roll from the putter, which has multi-coloured paddle grip and is available only with a 34-inch shaft.

The Ping iWi D66 putter

Hunter Mahan, Americans' most successful Ryder Cup player in the 16.5-11.5 defeat of the European team at Valhalla with 3.5 points (two wins - three halved matches) has revealed he was using a prototype Ping iWi D66 putter.

"As soon as I grabbed it, it just looked good to me," said Mahan, who rattled in a match-turning putt at the 17th hole in his halved match with Paul Casey. "I like the feel, the set-up and the way it's rolling for me."

The iWi D66 uses interchangeable weight inserts. One of the two 12-gram steel inserts is placed near the heel; the other is on the toe. Golfers can use optional tungsten 20- and 28-gram weights to make the putter heavier, if required.
