With a quick set of the wrist one must be using a pivot controled hands which I thought was more a Hitting Motion.
No...you can use sweep loading with both procedures...with hitting you can only use sweep and random loading not snap loading. Why? With snap loading you need an "End Assembly Point"...for a full stroke with or without an extensor action takeaway, the stroke ends at a "Top Assembly Position".
I sure don't recommend it because of the early wrist cock which I don't like. It also forces you to cock your wrists kind of violently which feels unnatural to me. The only other benefit is that it tells you about your speed in the impact zone (balls fly out and clack). I get the same effect using a device called the swing rite (original) and you can adjust it so you can build up speed at the impact zone so I would recommend that device over the swing setter.
