2 pairs - blue and red. Blue pair starts of as thrower and dump. Red pair starts off as front of stack and another stack cutter, Force is sideline.
Dump cuts upline
Dump cuts back to receive dump pass in middle of field
Front of stack cuts for swing. Continuation cut starts moving
Continuation up the break side.
Setup for next iteration. Disc should be near the sideline from continuation cut. Swing cutter (R1) becomes the dump. Dump (B2) becomes back of stack and original thrower (B1) becomes front of stack.
Run the drill going in the opposite direction.

Reset back to beginning but players should have swapped roles within their pair.
Repeat - Variant 1 - No break side swing
as normal version
Swing pass doesn't go, either because timing was off, or D prevented it
Swing cutter (R2) cuts back to open side
Continuation cutter adjust and cuts to open side for contination
Reset but disc starts on the other sideline from normal version of drill.
Repeat - Variant 2 - Give go
as normal version
Instead of dump throwing swing pass (perhaps their defender gets round to stop it) they instead run an upline give-go with original thrower since they should be easily able to get clear of their defender
completion of give go
Continuation to open side. In this variant the front of stack doesn't really do anything but could cut back to be a backup option if the upline cut doesn't come off
