Yeah, I tried to get in it for a bit, but ultimately started getting more serious about Speedcubing (Rubik's cubes). Even easier (or at least lazier) way to keep your hands busy :)
I do have a couple of "serious" Yoyos, including a OneDrop, that I pick up once in a while, maybe one day I'll get back into it for real.
A few of them are OneDrop, including a Kuntosh near the front, and a Summit a bit further back :D
