So, Here is a picture of an iron. If you put down the club "correctly" when the buttom/sole of the club to the ground. You should able to see the club from the side like the picture above. Every club has its own design angle(Loft and Lie) plus the Bounce(I will mention later). The loft of the club will affect to the trajectory of the ball will flight. The higher(More open) the loft is, the more higher the ball will flight.
However, not every golfer created equal. Therefore, swing will change from player to player. Some golfer will always hit the ball higher than others even they are using the same club. Why? Because when the club-face made the impact with the ball, the "effective loft" is what really counts!
Example:
Lets say that my #7 Iron loft is 34 Degree.
I suppost to hit the ball with 34 degree when impacting the ball. However, I rotated my wrist too much open when I am hitting the ball. therefore, the real (effective loft) is actually 39 degree. So now the ball will flight 5 degree higher than what it should be.
34(Original Club Loft) + 5(My wrist too open) = 39(Real effective Loft)
So, if I complain about my balls flight too high, I can try to get a set of iron that is designed stronger(less Loft). In many case, it will be the LT(Low Trajectory) series. Maybe in the LT series, the 7 iron is 30 degree. So with my open wrist hobby, I will get 35 degree effective loft.
Vala! The balls flight about the right high now!
