But more importantly and again, you can't use a stack and tiltish pivot (pivot, not arm swing) AND lean the shaft a bunch and expect to hit drivers anywhere other than off the volunteers head in the right woods.

Why?

Can explain the mechanics that this pivot would have on the golf swing. I look at say Sergio and I see a very centered (stacked or whatever its called) and it seems to work well.
