You can’t unscrew it, so you have to use a pin or something to get knots out.
I keep a safety pin on my CLWY Snapback xD
You can unscrew to unstack/change bearings/new response etc. but it’s too much work to do it just for knots.
You can it’s just when you do the stacks come off because unlike a normal stacked yoyo this doesn’t have a nub coming off the yoyo for the stacks to stick on.
Oh ok thanks. And back on topic, I now hate hub stacks but love z stacks. I used a G5 and its soooo easy to catch. I might have to buy some z stacks or a G5. Regular hubstacks are cool but I will never learn how to use them. I do think it’s cool though that people can hubstack a DV888. Gives you options I guess
