The active cutting pair depends on where the disc is. If disc is on 1, cutters #4 & #5 are active
There is no hard rule for which cutter should go under/deep. Communicate who should initiate and the other should just cut the oter way
Ideally, the furthest player in the handler space should clear into the stack. Cutters will move accordingly. Very important that everyone is communicating this to each other here.
Say player #4 reset the disc to player #2. Player #4 should still remain in the handler space because the initial handler (#3) has cleared into the stack.
Now cutters #7 and #3 are active and will make their cuts accordingly.
If the stall count is not high and the handler is not looking for a reset yet, the far player in the stack (#5) can strike across under or deep if the active pair has already completed their cuts and cleared off the space. It is very important that the space is clear before #5 performs any movement to avoid clogging.
When near endzone, a vert stack will most likely be called and a standard endzone play (cuts from back/handler calling the 10,20,30,40 play)
