Clubface alignment at setup for hitters and swingers

[bendet3]

Could someone remind me how it is recommended that you set up your clubface (ie. slightly close, open, square) for hitters and swingers for a straight, full shot. I thought that I remember reading that it is different for hitters vs. swingers and long irons/woods vs short irons.

Moe Norman set up with his clubface "half open," about 18" behind the ball. Nicklaus set up with his driver face a few degrees open.

Is it not simply a personal preference based on comfort, adjusted of course for the ball flight desired.

Re the Allenby posts: Note how his coach and Robert arrived at STRAIGHT trajectory as the norm, with options for working the ball.
