Slitting a circular sleeve lengthwise and compressing it, produces an oval, not a smaller circle. This would produce tight and loose spots in the ball travel.

Thank you for the details. I've seen that technique (If I'm

was an interesting approach. Wondered why it didn't see wider use.

With your endorsement here that will likely change,
