@NegotiableGolf Sure golfers hit their 7 iron farther then in the past but today's lofts are so reduced, that 7 is between a 5 and 6 iron on older clubs.

Tim Cusick, PGA
@timcusickgolf Rule of thumb on 3woods. If your clubhead speed is less than 85 mph carry 5 wood and then a 7 wood. Better chance to get the ball in air.
@TitleistEurope Joel Sjoholm, Voke and Leigh Davies chatting about New 712 irons. http://yfrog.com/h4t9pfij 
@TitleistEurope Titleist ambassador Mark Haastrup tried these 712 AP2's on the range today.. http://yfrog.com/hskw7jlj

@Graeme_McDowell Good days work at Castle Stuart. Tweaking bag set up for next week. 3 hybrid replaced with #Srixon 2 iron. Lower bounce on my #Cleveland 58.
@Graeme_McDowell RT @AdrianByrne555 novice golfer here, why 2 iron in bag over 3 hybrid >> low ball flight which is better in wind & running on firm fairways
