I understand I asked the question before, but I haven't gotten any responses I quite expected. I want it to be like REALLY fast, furious, and fun to play. I've been playing the piano for seven years (when I was like six or something). With this piano piece, I really want to test what I am capable of and what I need practicing on. Because my puny thirteen year old hands are still growing, a piece containing a lot large octaves probably won't be the best choice, but all suggestions are really appreciated.

Thanks in advance!
