Iron Shaft Length Increase

I am having my Titleist irons reshafted. I like to increase the length of the shaft about half an inch from the standard length. Should it help me increase my drive distances?

Rolando,

If you can successfully hit the longer clubs on center, the answer is probably. If not, the answer will be no. A fitter could give you different length clubs to see what works best prior to making the length change.
