Wow!

That's an amazing swing performance considering such a heavy unwieldy club.

I am therefore not surprised that he had difficulty keeping the club on the elbow plane during the followthrough, considering the effective mass (momentum of the heavy club) as it passed through impact.

What impresses me is that he kept the club near-perfectly on the elbow plane during the takeaway swivel and the release swivel phases. The fact that the hosel remained on the elbow plane during those two swivel phases surely suggests that the hosel doesn't rotate to/away from the sweetspot plane when it travels below waist level.

Please keep my feet to the fire. All my personal opinions need to be critically dissected for logical coherence and their degree of consonant concordance with objective reality.
