Pool cue systems are disclosed which include at least one graphical icon on the pool cue shaft adapted to be observed within the shooter's peripheral vision while shooting pool. The icons are preferably aligned along the longitudinal axis of the pool cue shaft at predetermined distances indicative of game parameters, which are stroke lengths, bridge hand locations, and stroke speeds. The icons are adapted to enable easy peripheral observation of pool cue stick motion while shooting pool with the eyes focused on an object billiard ball. The icons may additionally be decorative. Methods of use, making, and doing business are integral to the pool cue systems.
