The shaft's weight is the number one factor that controls the total weight of the entire golf club. Lighter total weight equals the potential to increase the average golfer's swing speed, which equals the potential to increase the distance of the shot. If gaining more distance is a primary goal for the average golfer, they should definitely be fit with the proper graphite shaft design in their woods and irons to match their swing. On the other hand, if distance is not the main focus for the average golfer because they already have a high swing speed, if they like the feel of steel and their swing tempo matches a little better to the higher total weight steel shafts bring to the clubs, then steel is the better option.
