You must know exactly what you don't like about any particular cue before you can find one you like.
If you don't know what you dislike, try out some cues so that you can figure out what really just does NOT work.
Only then will you be able to figure out what you really want.
If you are sold on OB shafts, then the weight, balance, size and feel of the butt will mean a lot more than whether a cue is "custom" or "production".
