[O.B.Left]

I know a lot of A.I.'s used to teach holding a flat left wrist through to finish (with perhaps a little bending in finish swivel). But did this come from Homers book or from some A.I.s?

Lynn Blake teaches something different. A bent left / flat right in finish swivel , bent left /bent right at finish. Just like you see on tv. In fact Lynn teaches a geometrically flat , flat left wrist at top, which can be different from a literally flat left wrist . Flat at impact? Absolutely. Bent shortly thereafter .... maybe if the shot demands it, a type of short flop shot comes to mind. Intentional throwaway.

Homer said that a lot of pros were in the process of throwing the club away , that they were experts at it. And that so long as the club head did not pass the hands prior to impact , the law of the flail held and the shot was not necessarily lost.
