My channel is dedicated to a study of the Classic Full Roller bowling style of the past. This is the way bowlers of the past bowled like the great Ned Day and Billy Hardwick.
The two most critical things to remember that identify a Classic Full Roller are:
1. The ball track of a Full Roller rolls over the full circumference of the ball. The ball track will be diagonal across the palm of the ball between the fingers and the thumb. My channel ICON depicts this.
2. A Full Roller's ball has no axis tilt. Imagine the Earth laying on its side with the North and South poles pointing to the sides, that is how the axis of a Full Roller's ball looks as it rolls down the lane.
3. Even though a Full Roller has no axis tilt, they can and often do have axis rotation.
