Glue on or Screw on Cue tips?
Cheaper Cues have Screw in tips, Better Cue have Glue on type.
Screw tips have a plastic base and a hollow thread in the brass sometimes making a small vibration and a less consistent shot when hitting the cue ball. Screw tips are best for easy quick changes like in a pub or club environment.
Glue tips are directly glued to the timber on the end of the cue with a brass ferrule holding the strength at the end of the shaft. This gives a solid more controlled experience.
