Definitions- Back to Basics

[12 piece bucket]

For me- using TGM terms - Pure=True

That's 7-2 - True Swinging or True Hitting.

Pure Hitting would be when the acceleration method- pushing - automatically aligns the clubface. As opposed to "Hand Manipulaton", i.e. consciously or subconsciously- making sure you arrive at impact with a flat, level and vertical left wrist - assuming that you took your grip that way.

Vertical to what?
