Swing Weight on Driver

[Daryti]

Found out that most Japanese made drivers (Yonnex, Royal Collection,...) have a swing weight very low compare to US made, usually D2 to D2.5 while US made is D4 and even D9 for taylormade 2.0 Burner. Any particular reasons or advantages? Body built, height?

I try the New Yonnex 450 driver 9 degree with NP 50 stiff shaft and it feels light and more control.

it feels light and more control.

Care to expand on this ?

The shaft is probably less than 50 grams, and the head is very light compared to Burner, making the swing weight D2.5. On the backswing just do the motion RFT and easily, if the shaft is heavy I feel needing more muscle power to bring the club up thus may result in jerky motion.

Swing weight has little to do with the
Total weight of the club.
Well not really- but it's function is not to.
The new clubs almost make it useless.
I am a little old school. Woods 2 weights higher than irons.
I think for swinging the higher weights for the same club mass increases the throw out speed but I believe the average player will adapt to a change in swin eight easy. But mix and match bags can be problem.
