The whole too high/too low discussion is over my head, but maybe Haruka's toss got lower when she stopped jumping? I had to do a double/triple take to be sure it was Miyashita in that video. She isn't like that any more. What a beautiful connection with Miyu. It has that "I know what you like" quality
I wonder if setters that jump too much are prone to spinal injuries. Sato also suffered from that and Takeshita was saying something about being injured at some point but I don't recall what it was
