Just bought a set of these and have yet to take them out on the course. However when trying them out on the range I was easily hitting much further and decidedly straighter. I also picked up a set of mizuno clubs but the Di7's clinched it easily. Not only are they brilliant functionally, they also look great too, meaning that when you stand over the ball, you have that extra confidence that comes from having a nice, shiny good looking set of clubs!
