I like a full splice cue, 19 ounces, wood to wood joint, 11mm shaft, milk dud tip, 15 inch pro taper, stack leather wraps.
The hit I prefer is the "normal" one a full splice butt provides. Has resonance and comes up through the shaft into the butt and makes a sweet sound and pleasant vibration. I like the milk dud tip as it is plenty hard, which I like, and puts english on the ball easily. The hit should be crisp. One fellow commented when shooting with one of my cues that it felt like he was "sticking" the ball. If that makes any sense to you, it's the feel I like.
Also, although the shaft is only 11mm, with the short ferrule and milk dud tip, the shaft doesn't feel particularly "whippy" to me, although others will disagree. Obviously, the quality of the shaft wood is key to having a firm hit with such a slim shaft.
