yes . But the fashion/technology seems to move : the last 2012 carom models from Longoni are coming with pins in the buttBilliard cues seem to be pin in shaft.
Why would it be more expensive or difficult to plug, drill & re-tap or add an insert to a butt versus a shaft???
The one lingering thought I've always had about this subject is the fact the late, great cuemaker Burton Spain built his cues with the pins in the shafts... because he felt that produced a superior playing cue.
