Do we REALLY need longer shafts?

[metallion]

I remember reading an article about Jack Nicklaus. The title was "All I know" and had some 100 observations that Jack thought was the most important about the game. As far as I can recall one of them was "most golfers should use normal length shafts".

I went to a clubfitter. He looked at my swing and I ended up being fitted with shafts a whopping 1,25 inches longer than standard.

Maybe I wanted to be "special".
Or maybe I wanted a trick helping me to play better.

Either way I bought his advice.

Fast forward while learning some about TGM.

Looking at my swing video it was clear I kepy my right shoulder too high. Eventually resulting in pulls. I started suspecting my clubs.

And today I found a fitters station where I could grab 2 6-irons same make and type as my current ones. Only that they were regular length and 1/2 inch extended respectively. The latter 2 degrees upright.

Result. I hit the regular length and 1/2" extended irons far better than the ones I carry. Straighter and Longer.

So I am looking for a regular length set. For sure.

And opinions...
