I really like this set. It is a great idea and works really well. It doesn’t really vary much between different productions but they all look good and work flawlessley.   As long as the center is designed and built well then the stage will work, but say the center was off at an angle on one side then it would either jam or turn with a huge wobble. The smallest error at the center would be blown up at the edges and become quite noticeable.   I would love to get a chance to build something like this. In essence a simple idea but all together quite complicated.
