The reason I say this, is because the fabric outer covering of the Trackballs will not result in a very good seal as the nice one layer vinyl tube would last year.

If you tried this, you would probably need 2 or more on quite opposite sides of a ball, and in that case, why even bother adding the venturi mechanism when you basically have a gripper with 2 points of contact anyways?

Kind of what I was thinking...
