The Mercury has saved me many times. When the heads are dry, which is typical in one of the houses that I bowl in (and that is "Fresh" oil). The Mercury moves the easiest through the heads for me, while other balls start their movements too soon. I have the ball drilled about 5 x 5, and it still isn't snappy. It is definitely an arcing ball. When there is longer oil, I don't even think about using it. Overall it gives me good control on drier and messier light oil shots.
