So I was looking for a urethane ball, because of what I had been told about the motion, and, liking Storm as much as I do, I went with the Pitch Black. It works as advertised, up until the arrows, then it just starts moving and doesn't stop. Now I've watched other rev-dominate players use it and have it in control, playing down first arrow, but I try the same and I'm only hitting the seven pin. I hit it with a 4000 pad, and I haven't gotten to use it yet so I don't know the result. Do you all have any advise, for release, surface, etc, to tame it down? I have around 400-425 revs, and, due to a recent arm injury, I throw around 12MPH.
