Bought this ball 2 weeks ago, to use for heavier oil conditions. Needless to say, this ball hooks more than I expected. I am a lefty, so it is driled with the pin about 1/2" left of ring finger, with a balance hole. With my Eraser, I play over 3rd arrow, bellying it out the the 5 board before it makes a movgeto the pocket. With the X-It, I am playing over 4th arrow, almost to 5th arrow, playing out to the same point and it is still coming back. My normal house shot I bowl on is a 40 foot defence oil, about an 8 to 8 spread, with real light oil outside. I also am in a sport bowling league and the shot we are currently on, I am still playing inside, and the ball is coming back with force. I am still getting used to the ball moving so much, for usually I get my balls drilled for length, but that was not allowing me to get through real heavy conditions. This ball gets through the oil no problem. I have however left quite a few splits, but that is just me not playing the lanes to the full potential. Kicks out 7pins all day long however. All in all, a 9 out of 10. Once I play the hook more, it will be a 10 out of 10.
