Swingweight calculation ?

[3oneday]

I'm thinking of reshafting the Ping irons, i10's but the serial says they swing weight at D0.

They are standard length, with the stiff AWT shaft. I believe this shaft is 107 grams in stiff.

If I install some PX shafts, which I think are around 125 grams, and play them quarter to half over, can anyone give me a rough calculation on swing weight at all ?

I will also use midsize grips, does that many any difference whatsoever?

I read this rule of thumb on golfwrx last night:

1/2" = 3 swing weight points

2 gr club head weight = 1 swing weight point

5 gr grip = 1 swing weight point

9 gr shaft weight differences = 1 swing weight point

The heavier grip will reduce the swingweight rather than increase it.


EDIT - I have no idea how reliable this is. Just sharing something i read!

This should get you started.
