I said at AAM that Vitro didn't make swirls and then I said some of the vitro shooters got twisted up and swirly and the blue devils often had a flopped ingot which is I guess technically the most basic form of a swirl, but Vitro was not a WV swirl company and didn't make swirls. Now all these "Vitro swirl" posts come after I said that... Some of their patches got swirly but they weren't in the swirl market. Just because a patch type marble setup got out of whack or whatever and made some that got twisted around doesn't make it a swirl, it's still a patch, it just got twisted up. Same as corkscrews... they swirl, right? All the way around the marble, sometimes several times, but they aren't called Akro swirls. They were patches that then got twisted by the spinner cup. Well, some patches got twisted by the rollers instead of a spinner cup.
