No problem Slicepong, yes thats spot on you only want to aim more on the back of the ball when playing against backspin, for others as you mentioned you should be aiming to hit more on too of the ball and brushing over with quite a closed bat angle which naturally it has to be if your focused on hitting on top of the ball.
As long as you get a good acceleration and nice fine brushing contact then you will have no problem generating good spin quality on all your shots!
