Hand seperation question | Golf Monthly

I bow to the gods that is justone, oh and Bob too ...

But I'm surprised that inconsistent ball striking is being linked to lack of wrist cock / break
I can see why wrist cock can be good, but usually inconsistent strike comes from too many moving parts, not too few.
Personally I would be looking at excessive body movement /sway as a cause of inconsistency

But I'm not the pro
Be interested to see your swing vids though
