A fully-bent Ball might look like a heavy pipe (and it is), but the low center of gravity allows this one to literally hang in the jaw with very little effort. People, I think, pay too close attention to the weight of a pipe without taking into account the shape. Had this been a straight pipe, I don't believe it would be comfortable to hold in the teeth (more like impossible), but is an entirely different animal because it's bent. Hold two gallons of water - one in each hand - the left arm hanging down while the right arm is stretched and parallel to the floor. Your right arm will be mighty fatigued, while your left arm can go on for a long while.
