swinger and Single hand action

[12 piece bucket]

I see alot of pros use single wrist action ( or at least a delayed swivel).... the consequences are seen in the right forearm position at the top though ...no?

jack and flying right elbow?? is that a consequence of single wrist action?

It seems that with an early swivel/standard wrist action you can get your right elbow down in a position to load the shaft at end...all that stuff in 7-3 - right?

I'd say flying elbow is a combination of wrist action and plane angle . . . if you look at his wedges even though they are "high" the are aligned perfectly.
