This is our main/default endzone setup. B1 and B2 are the two handlers outside of the endzone, with B1 having the disc and B2 set up on the break side. B3 is at the front of the vert stack and is the main ISO (isolation) cut. B4 is going to set up his cut after B3 finishes and clears his cut.
B3 makes a cut, either to the force or break side. Do not dance too long in the space; make one or two main fakes and cut to a side and clear. Once B3 finishes his cut, B4 moves up and fills into the space.
