It is strong. In the US the only ball with it is the Cold Blood. I have one, I went with a 50 x 3 or 3.5 x 30. The ball is strong and smooth for me, needs oil. I had even polished it to try and use on our house shot, it was still too strong but that was also in part from the layout I chose as I couldn't get too far left with it otherwise I'd lose entry angle to the pocket.
