The latest Natural Golf infomercial shows a closeup view of the clubhead through impact with a strong closing clubface action. Since little else in their method would produce this geometry, is it not likely that a reflexing (inward) shaft flex action is responsible?

I have written often of the potential for Clubface misalignment as the result of Shaft Flex, particularly with the more flexible Shafts at higher Clubhead Speeds. However, since I have not seen the commercial you referenced or the Stroke that produced the Impact, any further comment would be pure conjecture
