I love doing the slapper from behind my own net to a winger on the boards. In many instances, they won't try to get behind defenders, but will make a quick or one-touch pass to a teammate in the NZ. In most cases, there's a defender looking to step up on the winger on the boards so making a quick pass gets the puck out of danger and leaves a defender out of the play.
That's good advice about slowing down. Being in a glide also raises your accuracy with passes along with putting the puck on your forehand. As you mentioned though, conserving energy is always good. When your energy drops, it lowers your stats overall so best to use hustle when you need it the most.
