There is another practical problem. If the cube is expensive, and replacement parts are not available, what happens if by speedcubing you break it?
You would need to make replacement parts if the internals are as delicate as they sound, and if those are expensive you have a whole other issue. Either way I will buy a 6x6x6 as I hope they hold up for speedcubing. Also, will the 10 minute time limit be kept? If so, I imagine not many people would compete, other than top level big cube people who have a fast solution with lots of practice. The 6x6x6 isn't as open to new people who have just figured it out. I mean is that just the nature of the puzzle, or should we extend the time limits?
