Vari-Loop with "The Doctor"

On one pole, the rope feeds through a hook and can be pulled towards the handle via a thread, thus shortening both top and bottom rope. Note: as the loop gets smaller, the ratio of top to bottom rope changes. However, I have tested it and in works quite well. It allows for a few interesting techniques, such as 'growing' the loop once the bubble is going, or 'shrinking' the loop - possibly to aid closing off (may be useful for super giants that can be difficult to close off).

Video explanation to follow.
