Shot shaping should always be an exercise practiced with simplicity by amateurs. I prefer to alter the setup including face angle position at address to create the spin required. Even professionals and experts (along with ams) should never be left in a bad position on course if the curve desired does not happen. Shape all shots with a purpose and a high level of certainty of the desired result and low risk for error. I warn against players shaping shots just because they THINK that is what the pros do.
