I have fooled around with grinds a bit. It is just so contrary to the way I think. I am always trying to get things to keep spinning, to continue to spin, to spin faster. Grinds, of course, do all the opposite. But, I suppose, that is part of what makes them so cool.
From what little I have seen, it seems like yo-yoers are more into grinds that top spinners. What do others think?
