If you can get what you want (kind of "hit", balance, weight, etc) from a production cue, it seems silly to order a custom ("Dear Mr. Custom Cuemaker, please make me a cue that looks and hits just like an XYZ Corp. production cue. Please find enclosed a blank check.").
For me the answer was an OB121 with a 30" OB2 shaft and UltraSkin Soft tip. Hit, balance, weight and appearance (sneaky) were exactly what I would have ordered from a custom cue maker. The nice thing with OB cues is that they're offered with four distinctly different shafts -- something for everyone.
If you don't know what you want either road is costly.
