Donald's doing tremendously well now in the world rankings, and if you've watched him recently you'll notice how good a putter he is with this.

What I really love about this putter are the two alignment aids that come down to the side of the putter. It's also known as The Fang, and you can see why.

This putter is also available in the centre shaft, and the great thing I always think with a centre shafted putter is that, if you're prone to missing the hole a little bit to the left, it'll help you get more aligned squarely to target.

It sits beautifully - really easy to align, and I think it gives you a lovely stroke as you come back and through towards the hole.
