Why New Clubs hits the ball Further?

So we all know the new irons hit the ball further. But do you know what is the majority reason behind the new "hitting further" secret? This chart should give you an idea about how the Golf Makers of the world play around from the past.

These are the average specs from different brands. They could be all slightly different due to different models.

As you can see. A 7 Iron from 1970 most likely have Loft Angle of 40 and Length of 36. Now you look at our 9 Iron from today, Loft 42 Degree and Length of 36. Is there something funny here? The club numbers are moving through time or we hitting further everyday?

And why we need a "GAP" wedge now? So from 1970 the gap between my PW and SW is 4 degree. Really! There is not a "big gap" it is quite standard. Look today's Iron. My PW is 46 and my SW is 56. My God! There is 10 degrees inbetween them. I really need something to fit into the gap! That is why!

Ofcause! I know the material changed and Tech really improve. That is also some factor of why we all hit the ball further. But the really improvement of the club is the forgiveness. Today we have a fancy term call M.O.I. (Moment Of Inertia) Which really mean that if I make a "bad" shot. I hit the ball somewhere around my sweet spot. I will not lose too much of distance and the direction of the ball fly will not be off completetly. Woo! That wil save my day somehow right?

So the question is that "SHOLD I GET A NEW SET OF IRONS?" The answer is most likely to be "YES". Because it will increase your happy days because it is really "more forgiving".

"ARE NEW DRIVER HIT THE BALL FURTHER?" The answer is also "YES" because most of the golfer dont hit the ball inthe dead center of the club-face. Therefore, we will find with the new driver, we dont"lose" much distance base from a higher M.O.I.

If you are a professional player. Always hit the ball at the sweet-spot and know what you doing. (like the people you see one TV playing for Million dallor) Keep using the new model of the clubs does not really help them much. They dont really hit the ball further by switching the clubs......Dont forget, playing golf is their job. They just pick the club which give them the most sponsorship money. So, Ernie use his new Callaway Iron now because it is much better than his old clubs? Hmmm.....I am guessing because he gets paid for using them? That is why now some people will be willing to pay for big money to use the same clubs that he used right? You tell me...
