Interesting point. In the Western 2HBH my left hand holds the grip like a semiwestern FH, so PTD should be more natural than it would be for an eastern FH grip. I'm not seeing it a whole lot on my backhands, but then again I am now trying to make PTD more of a habit on my forehand. I guess PTD is just a step I missed when first learning tennis
