A collection of stream maps in various bpms and styles that helped me improve, most of these have pretty high stamina requirements. Maps for those that have mastered the lower end of the stream skillset and wants to further improve.
Should be downloaded with both of these collection if you want to sort them into more finger control or more stamina heavy maps:
