New clubs or shafts

I got offered a deal a couple of years ago on a relatively unused set of AP2 710's.

I like the clubs but feel I should be using stiff shafts as opposed to regular.

Joined here as I know next to nothing about equipment and clubs as I generally just work around my budget.

Should I be looking at a completely new set or just to buy shafts to use with my current clubs?

What is your driver or 7 iron distance?

Thanks for the welcome

I believe I have the Dynamic Gold Regular shafts but will have to double check

Play off 6 -

7 iron distance approx 160-165

Dynamic Gold Regular shafts they are

Are they stiffer than usual regular shafts??

Any help appreciated

What is the 7 iron loft?

How often do you usually change equipment?

If you are satisfied with the trajectory and no directional issues, I would probably leave as and get fitted next time you upgrade. If you plan to keep the irons a few more years, and you are unhappy with trajectory, it might be worth investigating, but reshafting with higher performance shafts also means regripping, and the combination plus labor will knock a dent in the price of newer irons.

In the US, it would probably be around $30-40 or more per club. Of course new AP's are around $140 per club, but street price is a little less. If you sell yours that plus what you save on the shaft upgrade puts you close to halfway. On the other hand, if you are about to regrip anyway, the marginal cost for the shaft is a little less.

Sorry, you were probably seeking a technical answer. For me, if I was generally satisfied with the ball flight, the question in this case would be more financial than technical.

The Frequency Coefficient Matching measures (FCM figures in chart above) allow one to compare relative stiffness of shafts from different models and manufacturers.

The overall stiffness of a shaft is measured by the FCM. Although one of the heaviest lines of shafts, the DGs actually rate as below average in stiffness. This can be confusing, because DGs have stiff tips and - as boogie said -  they are heavier than most shafts.

The DG R300 has FCM = 4.8, whereas the Project X 5.0 (billed as the R flex) has FCM = 5.5. But, the R300 weighs in at 127 grams uncut, while the PX 5.0 is constant weight at 115 grams (prior to butt-trimming).
