is the dark magic responsive??
how can i make it as unresponsive as a YYF?? (if responsive)
Yes.
You can make it unresponsive by cleaning the bearing, adding shims, and siliconing the o-ring groove.
Actually, mine isn’t all that responsive if i have the two sides screwed in just tight enough to hold the bearing in place. It is responsive if you tighten the two halves all the way, but you wouldnt do that now would you? 
The Dark Magic itself isn’t responsive, but it can be.
Calling a yoyo responsive is really foggy if you ask me. A yoyo can be set up in so many ways, where some will be responsive and some won’t.
