where are you supposed to hold the button? wherever i put it, it feels like it's sliding and when I throw, it ends up flying off with the top. I know it's kind of a newbie question, but still. it doesn't feel comfortable at all, and even when just holding the button between my fingers before a throw, i can already feel it coming off. any tips? if you bought one of those aluminum cuper tops, that's the kind of button it is. before this, I was doing the whole yoyo knot thing. then I read it's not really recommended due to winding up the string before wrapping. so yeah, any help would be appreciated. I don't even know between what fingers you're supposed to put it in.
