Titleist have produced a big hit with their NXT Tour golf balls, new for 2010. Designed for golfers with a mid-low handicap, they are a great choice for anyone wanting to upgrade as their game improves but aren't sure where to start. A solid ball with a soft centre, the large core is layered with a total diameter of 1.58" and made from polybutadiene, covered in the thin Fusablend outer shell which is just 0.05" thick by comparison.
