The SuperDeker game is a top-notch training tool.  The person using the SuperDeker has options when it comes to how they train. They may want to keep the bands on or take them off depending on what that person is looking to work on. Same thing with keeping your head up. You would follow the same thought process as your other stickhandling training and would want to keep your eyes up as much as possible. Sometimes when you just want to have fun and maybe set a new high score, you can concentrate more on the lights and the puck rather than your peripheral vision. Once you get really good, you'll be able to break high scores even with your eyes up.  Looking into a mirror while playing will aid in heads up training.
