Fu Xi

The Fu Xi carries the name of a founding figure in Chinese mythology, and it sits at the top of Yikun's distance lineup as the glidey, workable option. Given real arm speed it turns a little, rides a long floaty midsection, and closes with a manageable fade, a recipe for genuine distance on backhand and forehand alike. Slower arms can still get hyzer flips out of it, but its best flights belong to players who can make a fast driver work.
