The problem with 0.4" is it isn't a definate mark on the ruler. I haven't gone MOI yet, but I did note that 1 cm= 0.3937008", really close to Dave T's 0.4". It would be worth your while to buy a ruler with cms. marked on it for MOI matching. This would be better than 1/4" which is only .25", or staying with .5" which is 25% more than 0.40"

If the 6i were your standard, then the 3i would be shorter than normal by just over 1/4", and the pw would be longer than normal by less than 1/2". Chances are your golfer would never know unless you told him. Also you may want to check a few of the lighter graphite iron shafts. I think you'll find a few where the balance point is noticeably closer to the tip than a steel shaft would be. That allows you to reduce weight and keep the swingweight (or MOI) up without having to lengthen the club too much.
