I own several cues, some are true custom cues made by single shop well known makers, some are well known " production" brands- such as Huebler etc. I have had more than 100 cues pass through my ownership at one point or another- a mix of the custom and the production variety.
As per playing with my cues- I will, at times, play with any cue that I desire for a given session; however, if I have a tournament or something lined up, I play with the same cue for a full week prior to using it for competition - I find that within a week of play - your eye, body, and mind will " learn" a particular cue, and there should be no surprises come game time.
Some people just enjoy pool - the game- others, like me, enjoy everything about cues as much as the game itself- I think that it is great to have two hobbies tied to the same pursuit. I could throw cue cases in there as well, fine crafted wood, leather , cases etc- another interesting aspect of a wide encompassing pool passion.
I do have a special favorite player- my personal purchase Richard Black Split Diamond model from 20 years ago - this one always feels the most natural in my hands, even to this day.
