I think I'd like to get into 2x2 speedcubing (I'm currently around 18-19 with the 3x3), but I'm curious about how good the cubes are. I recently got a Lubix Fusions (judge me, I know), and it's pretty awesome. Is there a comparable 2x2 (minimal lockups, no pops, really fast with good corner cutting) out there? Back... like, three years ago, now, I got a V-cube 2x2, and I had real trouble with lock-ups. Is that still a problem?
