Quoted from WaddleJrJr:Subways seem to be problematic with new/novice players. They'll be trying to watch the ball, and when the ball disappears they continue to watch where the ball was for it to come back, but then it shoots out from somewhere else and drains.
Flashers work well for letting players know where a ball will come from. But that's more cost for poor ole Gary. Subway, VUK and a flasher.
