One of my pool teachers told me, "Having a nice cue doesn't mean you're good, it means you're serious. It means you care about pool."
It means you can afford a nice cue.
I would add one more caveat to that. Having and playing with a custom cue means you have respect for the game of pool. You are raising the dignity of this game by using a custom made pool cue.
Silly
Respect for the dignity of the game of straight pool means you have a very high dollar custom cue which you only use when you play straight pool and, additionally, you have a nice set of highly polished balls like the Brunswick Centennials. You should keep these balls separate from your regular playing balls and reserve the Centennials for straight pool and one pocket. Another requirement would be for you to wear either a full two or three piece suit or, at least, a nice sportscoat when you play either 14.1 or one pocket. It's all about the dignity of the game
Sillier
I wish ALL pro's would play with custom cues. I know some of the production cues are perfectly good playing cues. But a top pro using a Scorpion? Or a Fury? Or a (I know I'm going to get flamed) Predator? Perhaps the sponsorship money really is that good. Cliff Joyner must be a superman at the table because Meucci knocks 25-40% off his game. If he ever puts down that Meucci and picks up ANY house cue, he'll know what I know. And Cliff will snap that Meucci with his bare hands
You are clueless
The pro's should toss away the baggage of playing with plastic and pick up a custom cue. Nice leather or Irish linen wrap with or without points. The pro players could increase the dignity of this game if they would use custom cues.
Most pro players are using production cues with a replacement shaft made by a mystery maker...

I suspect this, anyway.
Hey, custom cues aren't all $5k beasts either. To the lover of the sneaky pete's, Paul Dayton makes some outstanding sneakies at a great price with only a 4-5 week wait. You're going to love the way those cues play. I think Jeff Olnay's cues look great too. Probably play great. Ted Harris also. Mike Webb. Lots of great cue makers. John Madden comes to mind. Dick Neighbors. Jim Buss. Jerry Olivier. Philippi. Great cuemakers all.
Sugartree cues are fantastic plain jane custom cues. Then you find out that there are a lot of local cuemakers who deserve our patronage. There are more high quality custom cuemakers than I could shake a Meucci at.
That's how I think on this subject. Hope I don't get flamed because I'm not knocking production cues, I'm elevated the custom cue as an agent of dignity for pool.
