Stack sets up
One of 3 and 4 cuts in, the other cuts out to give the handler two options
4 doesn't get the disc so he cuts to the break side; 3 doesn't get a huck so he cuts in; 2 (who is now last on stack) cuts out; 1 moves back to allow 4 to rejoin the stack after his cut. Note that at this point handler has three options - incut, outcut, breakside. This is important as we try to cycle the stack to always keep these three options open.
4 rejoins top of stack; 3 cuts to break side; 2 cuts in; 1 cuts out;
The idea is to always keep this cycle running, even when the disc moves upfield
And keep doing it....
Again...
And again.....
