Due to the fact that a golf club has a lie angle, nessesitates that the club must be used on a particular plane during impact or alter the clubface to compensate for that deviation.
Whilst it would be nice to stay on this plane during the entire motion and is extremely advisable on chips/putts your going to have real troubles attempting a 'zero shift' too much past basic motion.
The 'ideal' would be to shift from the top of the backstroke with the club on the turned shoulder plane - to the plane the club design nessesitates.
Or have the club designed to match your impact alignments?
However, as much as Mr. Woods and others work on their backswings... there are obvious advantages to some over others.
So far we have... Steep is usually better with Hitting, and Flat with Swinging, although exceptions like Couples, Furyk, Nicklaus...Swingers, and Palmer(probably a Hitter) are out there.
Or have the club designed to match your impact alignments?
neil, do you mean adjust the lie angle ?
All golf clubs are designed for impact......I think.
