Actually The purple ice is my favorite ball of all time, although I haven't been able to use it in a year or so, since my center altered the lanes--new backends and have been putting out much less oil than they used to. I have 2 and the first one I got has a tame drilling on it...lots of length with minimal backend. To me this ball was kinda like a weaker mindnight scorcher--wouldn't over skate in the oil and wouldn't jump or snap on the backend, although the drilling I have on it probably had a lot to do with the non-jumpiness.
