When I look at your swing, I think that you swing is so good (and of such a high caliber) that I wonder whether your propensity to pull some shots to a small degree may relate to a few minor points.

Here is a simple diagram.



The green curved line represents the path of the clubhead. The orange dotted line represents the ball-target line, and intended direction of a straight ball flight. Red dot is the ball. Blue lines represent the hook-face arrangement of the clubface (exaggerated in this diagram).

To hit the ball straight, one has to take into account the fact that a golf club has an inbuilt hook face arrangement. That means that one has to place the ball behind the low point of the clubhead swingarc, and ensure that the clubhead is slightly open at the exact moment of first ball contact to ensure that the clubface is square at the exact moment of ball-clubface separation - if one wants the ball to go straight.

Could it be i) that your clubface approaches the ball minimally less open when you hit pulled shots, or ii) that you are hitting the centre of the back of the ball rather than the inner quadrant when you hit pulled shots, or iii) that your clubhead swingarc is not perfectly symmetrical to the ball-target line but fractionally open to the ball-target line when you hit pulled shots?
