+1 for the original poster. I'm not a driller, nor do I play one on TV, but I typically use nothing but symmetric stacked or even swung out and at least for me, when I moved the Cg to palm the reaction was noticeably different in the backend.... It may be a small difference to some, but respectfully, without knowing the OP's style of bowling, previous experience and hell, even that fact that it's simply what he ordered, his point is well taken.
