I think D is the stripped pattern with flying backends.
Thus one is usually going to need a lower rg ball with the backend drilled out.
ie hook set, cg out with a good reaction decreasing weighthole on the PAP.
The Vortex 2 or Clean will probably be sweet, while the Sweet may be sour!
You will have to play a defined spot in the heads and all adjustments will hove to go thru that narrow one or two board area at the arrows(2 and 1 moves will find you catching a dry patch in heads). To combat carrydown you will hit same spot in heads with a right move of feet and to combat flying backends you will hit same spot with a move to the right with feet.
It will almost be like when you used to always throw at 10 and just move your feet around that!
