Thank you to ‪@Blitzcubingg‬ for editing this out of my stream. This was a challenge I had thought of doing for a long time but I finally found a good way of doing it as a series of 3 streams. My rules were that the cubes had to be different designs, not just other versions of the same cube, I couldn't just use each of the 4 versions of the WeiLong V11 and count 4 cubes. It turned out that I just about had enough suitable cubes to do this. The reality is that I'm not sure how good an idea this is to be promoting that I can get sub-10 solves with so many random old 3x3s but I felt that it was a fun challenge and that people should be able to watch it. Should you still get the latest Gan cube from speedcubing.org? Yes, absolutely! But seriously, you may find you have more fun branching out into other unique puzzles, if I can solve these cubes in under 10 seconds then clearly they are good enough to get sub-10 on (and probably sub-6 if you are YiHeng Wang). To be clear, a single solve does not determine the quality of the cube, this video also doesn't contain my failed attempts at sub-10, you can see those on stream, the spreadsheet is here.
