This may be the Startburst Yo-Yo you are looking for, YoYoJam Patriot .

Best Organics?

Do you want to play responsive or unresponsive? If you like Old School plastic and you want Starburst response with an adjustable gap to play either responsive or unresponsive, than there is one yoyo that fits this description. An early 2000s YoYoJam Patriot. However the Cabal is very similar if feel, but its unresponsive with a step bump. [20200704_102825] [20200704_114434]
