Mark Crossfield answers the question - "Would I hit more fairways and lower my scores if I hit my 3 wood rather than my Driver?"
Some people find it easier to hit a 3 wood then a Driver and so might be tempted to shelve the driver and stick with the 3 wood. Mark says that it is fine if you are hitting the ball long enough. This is why the mini Drivers were made in recent years for this exact purpose.
