I have noticed that most production cues are balanced at around 16-17" and most customs are from 18-20". Why is this, is it because beginners cues are balanced more toward the rear, like a house cue? I like a cue with a 17" balance point from the buttcap, and the cues I have with the 19" balance point I have to hold almost to the end of the buttcap for it to feel right. Why is this?
