Mike O made some good observations recently on the matter. Can we try to simplify or would that be wrong? Can it be drawn? Might take two drawings one for each concept ?

What the heck is the Straight Away position?
Forward shaft lean with head soled square ? Will produce straight away ball flight?

HB ??

Yes but there's more: Ill try but jump in and correct me please guys.

Version 1 the more static consideration if you will.

-Its progressive as the clubs get shorter of course.
-its designed into clubs by the manufacturer and yet oddly its never mentioned.
-It moves the ball back of low point progressively. Note that ball placement as being related to the left foot is less relevant to the geometry . Note that it is possible to move the ball back vis a vis low point and by narrowing the stance maintain a prescribed ball to left foot relationship. This ball left foot constant is often written about , but seldom actually adhered to by pros. Their logic isnt as good as their instincts which interact with the physics of the matter . PHysics being inalterable . Its not golf physics its just physics.
-each club will now have a unique place where its sits square in its impact fix alignment (which includes a prescribed amount of shaft lean) vis a vis low point. There are differences amongst manufacturers . Trial and error is the only way of identifying the correct placement vis a vis low point. This is the Straightaway Position.

Why do they design clubs this way?

1. Shorter lever lengths switch ends easier, get to their impact fix alignment quicker, easier. Designing the club to sit square in an aft of low point position gives the shorter , faster levers less time ... its offsets the need for the golfer to swing each club differently given this lever length consideration.

2. Also there are benefits to an increased angle of attack on the ball . Hitting down on a ball is easier than the clean pick off which has less margin for error. A ball place back in the stance is a luxury that only the more lofted clubs can afford ... a hooded one iron played back in the stance would not loft the ball very high. And so one irons had little if any hook face as they were played up in the stance and swept off the turf.

3. I dunno.

Version 2. The dynamic consideration .

We need Mike O here. Version 1 and 2 are mentioned by Homer IMO. The amount of mass underneath the sweetspot on the face ..... the pie shaped section on a wedge say that is formed by the leading edge and a horizontal line running through the sweetspot.... given the tendency of the sweetspot to align to the number three pressure point implies a slightly closed club face at impact . A more dynamic form of hook face.

I might have screwed this last one up or done it a major disservice. When I get home Ill research it some more.
