Golfers can alter the weight of Ping's iWi Anser with a kit of interchangeable tungsten sole weights. The putter itself is made from 17-4 stainless steel, with a softer 304 stainless steel clubface, and it comes fitted with two 12-gram weights. As an optional extra, golfers can buy the weight kit for £39 with a pair of 20-gram weights and a pair of 28- gram weights, so the club weight can be adjusted to personal preference.
