In this video Mark Crossfield answers Dirk Bethge question from Facebook, “a friend of mine (11 Handicap) is fully convinced, he has noticeable distance with a Titleist Pro v1 (shorter) than a Srixon AD333 or a general harder ball. He talks about a noticeable differences up to 10 yards even with shorter irons. I am a 3 handicap and have never noticed such a difference. Which of us is right”?

Mark answers this and discusses the nuances between the different golf balls, how each ball might suit different golfers. Which golf balls do you use and why?
