Billy Ray and Crankin are correct. I have both the Big One and the One and am very familiar with the XXXcel (also a great ball. I have many others, The Big One starts up sooner than the one but as the others said, look out when it turns the corner. More ball than I thought it would be, I am still trying to understand it as I have only thrown it once on fresh a couple days ago after drilling it. Number one drilling but I am going to take the surface down or might have to move my weight hole down to smooth it out. Hope this helps, good bowling to all.
