This is almost certainly the largest 3x3x3 anyone has ever competed with in an official competition. Yes, this does slightly slow down my times but the delegates allowed it as I am not massively slowing down the round as I still average 15 seconds with it and I provided the special cube cover necessary to accomodate a 10CM 3x3x3. Unfortunately I did not quite achieve a sub-15 average but my average was still faster than with the QiMeng Plus M 9CM 3x3x3 last year.

The cube used is available here
