    Hi, Looking for help / advice. I’ve recently been fitted for 2 x 917 F2s and 2 x 818 H1s. They currently have Mitsubishi Tensei Pro Red AMC Senior / Lite shafts in and 12g Surefit weights. I have a relatively slow swing speed (60 mph I think) and have changed my AP3 irons to Ladies shafts as a result. I am thinking of doing the same for the woods and hybrids, but wondered whether that would also mean I should also have lighter weights in the heads? Thank you in advance, Katherine

    Katherine it depends more on if you change the length of the shafts, if you are staying the same length then you probably do not need to change the weights unless you want the head (swingweight) to feel heavier or lighter.
    Of course this depends on the balance point of the new shaft but if you stick with the same shaft in a softer flex it shouldn't be too much different.

    Hi Matthew and thank you so much for replying. I was thinking I would also have them reduced in length by an inch. My feeling is that I need a softer shaft for getting better launch and “feel”; and a shorter shaft for “manageability”. Would I need to change weights if I did that do you think?

    Katherine, following are the changes resulting for different changes in club specs:

    (1) +/- 1/2 inch in club Length = +/- 3 swing weight points
    (2) +/- 5 grams in grip weight = -/+ 1 swing weight point
    (3) +/- 2 grams in head weight = +/- 1 swing weight point
    (4) +/- 9 grams in shaft weight - +/- 1 swing weight point- will be a variance depending upon the distribution
    of weight within the shaft

    Also +1/- 1/2 inch in club length changes the playing lie +/- one degree

    So for example if your choice of shaft were 9 grams lighter and 1/2 inch shorter the swing weight would go down one swing weight point for the shaft change and 3 swing weight points for the decrease in length. Being down 4 swing weight points you could add 8 grams to the head or 6 grams to the head and a 10 gram lighter grip to get back to your original swing weight. Hope this helps.
