I never thought anybody took all that "sweet spot" stuff literally. The sweet spot is just a balance point--a geometric point, like a center of gravity.

There's an easy way to find a club's sweet spot. Just grab the shaft between two fingers, up where the grip begins, and let it hang in the air. With the other hand, holding a pen or some other fairly pointed thing, tap the club face repeatedly, starting at the toe and working back toward the heel. At first the tapping will tend to open the club face a bit, then it won't, then it'll start to close the club face. The point at which the tapping neither opens nor closes the club face is the sweet spot. You could even take a file and make a mark along the top, like a putter.

And speaking of putters, if you do this you my find that even some pricey ones are not marked correctly. That line may or may not be over the sweet spot.

Along the same lines, "forgiveness" is a matter of how much (or how little, really) the club face opens or closes when a given force is applied to it, a given distance away from the sweet spot.
