A Titleist staffer since his early days on tour, Spieth has stayed loyal to the brand ever since and tinkers with his setup as little as possible. Probably my favourite aspect was just how easy this was to line up. I holed a ridiculous amount of mid-range and short putts with this without having to rely on the usual line I put on the ball.

The second Spaniard and 10th European to reach World No 1, Rahm carries a full bag of TaylorMade equipment. He is one to add in new technology when it comes about and has a full set of the new SIM woods as well as the new Chalk Spider X putter. Day’s rise up the world ranking was largely down to a fine display of putting in this period and one of the reasons the TaylorMade Spider became so popular.As a Lynx ambassador Couples carried the brands driver and irons along with equipment from four other brands. Perhaps most iconic was his Ping Anser putter.

As a free agent Brooks had equipment from four different manufacturers in play when he reached the top of the world. Most iconic is probably the Nike Vapor Fly Pro 3-iron which he has clung onto ever since Nike left the golf hardware game. Rose had a full set of TaylorMade equipment in play as World No 1 including a full set of P730 Rose Prototype irons. Duval had five different brands in play when he became World No 1. I love how old school these Titleist irons look… The club head has been made slightly bigger and over the ball; this is much more confidence-inspiring.

A significant change comes on the sole; we no longer see the large weight plate, which means the new version feels lighter. If you prefer something heavier, you can adjust the weights though.
