Koc, what i know....

Though the 45 inch driver have 57-60 * lie angle, its more "hooked" than we know it ...

I think the trackman shows the ball can be hit on the downswing , level and even few degree on the upswing . we can play an 11* on the slight downswing or 8.5 on the slight upswing and get the same launch height but different spin numbers.

As long as we could get the ball leaving the face square to the path .. should hit a straight shot relative to where the path moves. say 4 deg to the left , but face square to the target .. 4 deg of Openness to path to contribute to slice spin.. thus it actually could be its easier to hook by placing the ball slightly back of stance because its easier to hit In-to-out path....

Regarding the side spin. the ball will have side spin and backspin. the wedge have the highest backspin and driver lowest backspin. But say given for both shot we have the equal amount of 3000 rpm side spin.. the wedge will give a small fade, but the Driver will give a pretty big slice. because the relationship, ie Ratio of backspin and sidespin will affect overall flight and if the sidespin overcome the backspin than the ball hits the neighbour... ie 3000 sidespin / 2000 backspin = 1.5:1 .. vs 3000 sidespin/13000 backspin... all physics... But the exact relationship... not so sure.. but you get the general idea why..


That makes the driver MUCH harder to hit. even much harder than a 3 woods. thus to keep the ball in the fairway, slightly higher spin is beneficial for driver. and higher loft ....

Though The driver being longer need a slightly longer time in order to reach the IN-Line conditions. Thus the "aiming point" is a touch back , OR , the ball position is a touch towards the target...

Hook Face too much incubation?
 

The sweet spot is behind the shaft on all clubs.

More so on the shorter clubs less so on the longer ones due to the loft.

Put your finger on the sweet spot of a wedge and see how far behind the shaft it is now do the same with a driver. Big difference.

Now with the wedge align the sweet spot up with the shaft (close the face until they are inline) and you will see the amount of "hook face" build into the club.

During impact the sweet spot aligns itself with the shaft producing the hook face.

Its that simple.

Great post
 

I agree I have rarely been able to get the correct feeling of extensor action, nor have i been able to really get teh frozen right wrist, love theidea of softening up the left side, most traditonal golf learning i.e taking swings with jsut the lead arm and hitting shots have lead to a very firm left side making EA feel stiff

Winner Winner Chicken Dinner!

Great post!

Great stuff. Are there any implications to the golfer? Any adjustments he or she must make? Club face alignment?

Thanks

I agree that clubhead COG lines up with the shaft at low point (not at impact unless ball is at low point)... but what are the implications with alignment and ball position of having drivers with clubhead COG more rearward than ever before??

Excellent question.

I'm guessing that the principle is the same - however not knowing much about golf equipment- I'd only guess that the actual COG of the Driver could be much closer to the face of the club than one would expect looking down on the club. In other words- looking down you might think it is "way back" in the center of the clubhead- yet based on the distribution of weight from front to back and due to the higher clubface versus the back of the club being lower or having less weight, etc. - that the COG may be a lot closer to the face and really not tend to close the clubface that much. Not sure that's right - just a guess. I do know that the question is a good one!

P.S. I just did a quck "longitudinal center of gravity test with a wedge and a driver i.e. lightly hold the grip with the forefinger and thumb and let the club "hang" vertically- and then see where the center of gravity passes through the clubhead i.e. the shaft line, the center of gravity of the shaft-head combo is surprising close to the top edge of my driver.

Although it would be good for an intelligent post to follow as opposed to this drunken guess that I've posted.

Did you have clothes on when you did the test retard?

Let's just say that I know my COG will be lower than yours!::o
