[Amen Corner]

I would like to know what a 'little head movement' amounts to in inches?

The smallest amount possible for you, whatever that would be.

This thread turned out to be a hot potato. I choose to start it under 7th edition changes and the reason was the additional text under 2H

: "The important thing is that the true Swing Center for ALL COMPONENTS is around a Hinge Pin with one end at the top of the Stationay Head and the other in the ground, precisely between the feet, with no regard for Body Location or Position at any time".

When I translate the underlined, you can setup with the head on different places. Lynn recommends to start from impact fix and let it stay there which sounds very sound/healthy. But thats an option, you could have it whereever you want but then leave it there and see what result you will get.

The debate about the SH will continue and trust me, there will always be different opinions on it. Try and Choose whats best for you.

Now, what I would like to know is why Mr.Kelley preferred the SH. I tried a few posts ago. Why has this additional text been put in?

If I translate it, then the pin will go right through the head, which means that it can rotate ( ala Nicklaus), as in 1L#2, which will make it easier to fulfill 1L#1, and as I posted earlier, you can always adjust your setup to obtain the SH.
