When I give a short game lesson the first question I ask is: "Which club do you use to chip with?" The normal response is either sand wedge or lob wedge. There is nothing wrong with a sand wedge or a lob wedge, however what I soon find out is that they generally only use one club around the greens. I never see anyone chipping with a 7 iron. Very often when I ask the person to describe how they imagine the ball will fly through the air, pitch and roll out, I see a shot that travels too long through the air, relies on getting a lot of spin and is difficult to control. The margin for error is big. The art of bouncing the ball through the fringe... at our course it is predictable, is lost. It does not get practiced either.
When you practice, leave the wedges in the bag and use your 7 iron, 8 iron and 9 iron. With a bit of practice you will find that you can control the ball better, with an easier movement. Weight on the left, grip down, ball position middle or back, keep the head still and let the shoulders rock. Margin for error becomes a lot smaller.
