You're probably right, Mizuno - I had a very flat swing and played the ball too far forward early on last year.

Now that my swing is quite steep (compared to what it was), and I've moved the ball back in my stance (overall), I'll have to see what happens if I place the ball forward (it would make sense that it would hook, as your swing is now coming back inside, and the clubface should be closed forward in the swing - in a proper in-square-in swing).
