Can i find it on bit-torrent ?
I been doing some thinking about this puzzle. If the main problem is to keep track of which twists are possible - it doesn't seem like a very good puzzle for me. That would be like the black hole puzzle, where most of the time is spent looking for the next piece. In short, puzzles with hard recognition i don't like. They don't easily lend themselves to speeding.
Am i the only one thinking like this? Of course i haven't touched this puzzle yet
