I don't flick. I try to save as much accumulator#2 as possible. PP#1 is the main target for my down stroke loading but pp#3 pressure is unavoidable. I try to drive the butt end of the club towards china or towards the ball or towards a point in front of the ball, depending on what kind of shot I am planning.
I read about Jim Furyk. He's using a double overlap because he gets a better transition. My theory of why is that it gives him extra Right Wrist bend - geometrically. This enables him to apply more pp#1 and less pp#3.
A "flick" reminds me of Fred Couples flop shots around the green. Very good but something entirely different.
Different deal . . . that couples motion you talk about is covereed . . . see Peck.
