If the disc in the middle, the iso can take 3 counts to get open.
If not, swing to the open side and cut up the line. #3 follows #1.
If #1 is not open, 3 comes back for the swing.
And then 4 comes out of the endzone for a swing continue. #1 sets up in the iso position.
Now 3 cuts up line, and 2 follows.
2 goes for the swing, #1 for the continue.
Swing to #1. #3 becomes the new iso. Repeat as many times as needed.
