An official rubik's 4x4x4 speedcube?
It's not officially a speedcube, but it IS a rubik's official cube. I have Cubesmith tiles on it, and I've been working on it for the past 3-4 months to make it amazing for turning. It's not loose enough that it pops at all, but it's very very easy to turn with.
I've put a lot of work into it and just wanted to see who would be interested in such a cube? I got a couple of eastsheens that I like and I use them more than I do the official 4x4x4 for speedsolving *preference* but would like ideally to get another 3x3x3 speedcube.
It does still catch on the odd occasion but that's somewhat to be expected, but I have a video here that you can view to see how it works
