the ball actually has a very smooth roll.. you throw it it starts to turn 60% down the lane and is winding up and then just jumps into the pocket usualy destroying the deck.. you throw it and then the axis rotation changes and then the ball moves.. its a quality ball, i would pick one up if you still can, if you have 100 dollars i would get the brunswickpba ball off of amazon.com its 99.99 and it is the original inferno with new colors thats all..
