It's always been a secret as to why I could shoot great with my cue and nobody else could.
I had a 1969 Adam cue. It has a logo on the butt.
I learned pretty quickly that my cue tip was a little bit warped. When I first got it, I'd hit a great shot, and then a crappy one. And another crappy one. And then a good one. It was just odd as I had been playing pool since I was 10 years old. I was never that inconsistent.
Rolling my cue didn't really show the small warp because it was right at the end.
It didn't help that my cue shaft was well-worn (I found it in a parking garage) by the previous owner(s). It was 12.5mm at the ferrule but 11.5 six inches back.
Well, one day I realized it had a warp. I set the warp so it curved up and took the shots. I was doing pretty good with it like that. So, I looked at the butt and saw the logo was at 10:00. So I every time I shot, I just had to set the logo at 10:00 and the warp was up.
Hand my cue off to someone else and they couldn't get a consistent flow. It made me look like a much better player.
Once I told my pool buddy about it, he tried lining up the logo and he could shoot much better with it.
That cue was stolen about 20 years ago and it really pissed me off. At the time it was only worth, maybe, $150 but it was the cue I knew. I've bought a couple replacements and someday I'll get out there and dial them in. One of the replacements has a slight warp just like my old one. The logo clocks different, though.
