Another thing I realized about Yau versus Redux...
Simplicity. Drilling either one is a job in itself. But...
Transitioning from one to another and getting good at both should be respectable. Not that I am trying to get more attention, but I got a 57.73 solve today on 4, and that was a 2 second penalty. I got a few sub 60 solves today! And I believe that I can transition from one process to another with ease!
