RE: ShopTalk: double weenie shaft

True, but bend angle is at the mercy  of shaft flex, particularly near the head, location of head cg, length of shaft and length of golfers arms.

One must either do the numbers or conduct tests to make a comparison of all users. I have written the equations for such bending and the head CG cannot move beyond the original shaft position, however, the radius of curvature in the vicinity of the head tells a big tale.

It's all fun.

The same laws of physics apply to both but the forces that the slow swinger generates, that affect these results, are significantly less then for a fast swinger.

That's correct, the laws of physics do not apply to slow swingers, only fast ones.

Getting the ball in the air has nothing to do with shaft stiffness except for the timing of getting the shaft back to straight especially for the slow club head speed player. I have successfully put to may low club head speed players, that could not get senior shafted clubs off the ground into stiff and X stiff shafts, that were instantly surprised how much better they could get the ball up. If they have a short handsey swing the soft shaft will have the head de lofted at impact while the stiffer shaft will react quicker and be back to straight. If the shaft is soft and you hit the ball above the C.G. you might get some loft increase but the slower the swing speed the less this affect. Back weighted woods will also give some increased loft because of centrifugal force pulling down on the weight but again the low club head speed player generates less centrifugal force. Most of these golf myths are based on high clubhead speed players and! ! ! ! do not apply especially to low clubhead speed players.

Hi,
Ed, Chris, Lloyd et all,
The SK VIP LL is about as soft of a shaft as I have come across, I took a wd shaft and measured 205 cpm gripped in a 5" clamp at 45" with a 198 gr 280 cc head.
I used the same shaft and mocked it up in a Seahawk VI 5 iron weighing 257 gr's at 38" and got 211 cpm's gripped.
If my math is correct that's almost a minus 5.0 freq.
That ought to be about soft enough to get bunts airborne.
