X4 starts drill by skating with a puck around pylon and takes a shot on net
When x4 crosses the blue line x1 in the opposite corner starts without a puck and skates around pylon at the blue line
After x4 shoots on net he then proceeds behind the net to pick up a loose puck and pass it out to x1, who is now rounding the pylon at the blue, for a one time
Drill continues perpetually
