Similar in concept to the 324 shaft but thinner with even less deflection. In spite of this I do not like the Z as well as the 314. My issue with the Z is that it is less forgiving if you apply too much English. If you like using side English the Z shaft will spin the cue ball like no other cue I've ever played. My style of play is more traditional and I rely on vertical center ball hit using speed variation for position. Like the 314 the Z shaft can be had in different joints to fit any cue butt.
