Umbrella in excalibure

You should start with a direction change.

Just after this change, pull rapidly the diabolo to the up and right, as the "umbrella" (see pre-requisite)
and you can make this strong pull, rapid movement from right to left and left to right as long as the diabolo does not tilt too much. Before each strong pull, you should damp a bit the diabolo, this improve your control and allow you to minimize diabolo's tilt.

 To finish, just make a straight movement more round to the right, and make a normal wrap to accelerate your excalibure. This is totally the contrary as the start.
