Driver length should be a dymanic fitting process so that you can find where you middle the ball in the face most of the time. Its no good hitting the sweet spot way out there once a round for that 300 yard down the middle effort and have the rest go bush.

Look for the longest average drive vs the longest drive and you will find that giving up 5 -10 yards will save you lots of shots.

Irons wise its still all about sweet spot striking. As long as you are not reducing clubhead speed and killing a comfortable stance then 1/2 less (or more) is not going to hurt much but could improve the scorecard a lot. Also consider 1/4 inch changes in the shorter irons vs 1/2 in the long ones. You will find a particular length where going shorter does not improve the dispersion pattern much.

For Drivers or irons, invest in some impact decals or just get some talc and see where you are hittng the face.

I cut down many more drivers than I extend. From memory Tiger plays with a 43 3/4 inch driver. Most OEM drivers are 45!
