Well, yes, yes I did

But the story is that premium chalks are just better in general.
If I can go 30 shots with extreme English, after only chalking once, my confidence level is really HIGH if I just chalked before the shot. I've seen SVB miscue with Masters in the COC event that was just on ESPN, and he JUST chalked. He even laughed about it and said, " I thought I chalked". The he grabbed the chalk again and really "drilled" his tip with it. And replay's on my DVR in slow mo showed he did NOT miscue because of his stroke or hitting the table first. Almost cost him the game.
But it's also the mess. Less staining on your shafts, hands, cue ball, and your table. I practice at home a lot. If you can shoot dozen or more times with any premium chalk, thus the chalk is "sticking" to the tip, less chalk everywhere else. (except Kamiu, that stuff is the messiest chalk on the planet)
But, it's like anything else, use what you like, and just keeping shooting pool. Just like Maple vs LD, or custom vs production, custom case vs production, Leather vs Linen, shoot with what makes folks enjoy the game :grin-square:
Just bought my first custom case, yep, from JB
