Should you change your Driver loft for winter golf?

In this Question and answer video, Shaun Tuck asks Mark Crossfield, "Do you change your loft on your driver for winter? How do you work out the best loft to use?"

Some people believe that you need to carry the ball further in winter due to the lack of carry on the golf ball. Mark has looked into this and found out that carrying the ball further doesn't actually make any difference and you are far better keeping a consistent swing throughout the year. What are your experiences of winter golf and how do you maximise your distance off the tee?
