Can you say a bit more about feeling a fade in the right thumb?
I think that if you are using the Manzell 'neutral' grip, then you can work the ball off of the position of the back of your left hand. With a draw you roll the hand over just slightly (horizontal hinging but with the clubface closing just slightly earl); with a fade you do a bit of angled hinging, holding the face slightly open. I understand what you mean about feeling the draw in PP#3 - I feel this too. Although I think I 'feel' a fade more in the left hand as I hold the face slightly open through impact.
