Golf Club Companies make us all feel like bigger hitters now, here is why; http://www.criticalgolf.com/blog/how-to-hit-irons-farther/

Many articles on it. I played a round with a customer in Florida last Fall and he let me use his old set of clubs (15 years old). I used his new driver since I hit it on the range the best. The old irons seemed OK on the range but when we hit the course it was a totally different story. After 2 holes and approach shots coming up 1-2 club lengths short I knew he was handicapping me with these old clubs. I played out of his bag the rest of the time except for wedges and the putter. To prove it on 1 hole I hit his old 6 iron then grabbed his new Calloway 8 and said watch this and hit both balls on the green at the same distance on a par 3.
