Just watching the British Open and TV Asahi ( A Japanese Channel) is going on about how Ryo has a prototype #0 iron in the bag today to combat the winds. Compared to his 3 wood, the 0 iron has 16* of loft and creates a penetrating trajectory with run thanks to an orange colored Tour AD iron shaft to stay out of the wind.
He tee'ed off with it on hole number one and took it over 250 yards. It'll be interesting to see how the club works for himin the Future.
This Could be the start of a whole new trend.
