I think....for what it's worth...Lol...that if you had a cue custom made for you, that you should play with that cue for at least as long as you waited for it to be built. Now this is excluding those long-waiting list cuemakers, such as SW, Searing, Szamboti, Tascarella, etc. Those cues don't generally have a 'turnover' rate like those cuemakers with shorter lists/build times.
Example: I waited a little better than 6 months for my cue to be built. I will play with it religiously for those 6 months before I will actually think about something else. So far, I am getting more and more in 'tune' with it, and am pretty happy, after a tip change particularly. I am not gonna say that I will never part with it...because I thought that about my first cue from this maker, and I did eventually part with it, but it was to order this fancier one. I actually had great angst parting with that cue. But currently, I do not anticipate parting with it, unless something comes along that just blows me away. I have a very definite idea of how I like a cue 'feel'.
I also think....again, for what it's worth

....that those who have multiple playing cues are often a bit too quick to judge on a newly acquired cue, because I don't think they have a real definite idea of what they want......they are just too all over the map, so to speak.
If I would have judged my current cue immediately, I would have been disappointed. I went to a completely different joint and ferrule combo than I had before....and it was 'odd' feeling at first. It also came with tips that I just couldn't do a thing with. Two months, and a tip change later.....and I am very happy with this cue. I have a very clear idea of what my next cue will be, and from whom, cuemaker-wise. But I am not making a definitive exclamation about my current cue for at least another 4 months or so. I am leaning towards this being a real keeper, but only time will tell.
BTW....this is all in reference to 'playability' and does not include 'workmanship'.
