If you use a symmetric ball all you're doing is moving the statics around allowing an x-hole to be placed in an unusual location... I still say, as have other who have done this layout, that it only makes sense to use a ball with a factory marked MB or one with an intermediate differential above .010.

I'm done with this discussion here since it's completely off the topic of the original post.
IMHO these "trick" layouts are a dead end for the vast majority of bowlers out there...
