The UWW World Championships went down last month in Azerbaijan. It's a little-known tournament, but draws many competitors from countries around the world to compete both gi and no-gi. 

You won't recognize any of the names of the competitors. Every men's no-gi final except one featured a Russian athlete. 

The rules are different and allow for reaping the knee (but no heelhooks). There are takedowns aplenty, and lots of dynamic movement.
