I have drilled some balls in the past with the cg left of my center of grip, doing that smooths out the ball reaction. I normally would only use that on short patterns or medium patterns that require a lot of control down lane. With the right ball, that layout could be good at the Open Championships this year. I personally would not use it on a Marvel because that ball is already smooth for me. For me, it would work better on a Victory Road Solid or even a Crossroad.
