Here are two training aids. Best of all, you don't have to buy them. Youalready own them. They are...

Your eyes!

At Impact Fix, you have one particular view of the Ball. If that viewchanges during the Stroke -- that is, you can see a little more under it (or alittle less) -- it is because you have moved your Head! So, establish your'view' at Fix, and then keep it.

That is the reason Homer preferred the Head as the Pivot Center and not itsalternate, i.e., the 'Point between the Shoulders.'
