2 7 9 10
This is a restep of Mad Matt's Feats Of Valor chart. It's a catchy track, like some of Elwood's other stuff. Expert is a hard 10; there's a fair amount of broken stream, and a few 32nd notes that are tough to hit perfectly. I actually played this about 10 times in a row to try to hit it decently. Hard is a fun 9. The steps flow together nicely, so it's not too tiring or jarring. Medium is also fun, as it has quite a few easy 16th notes.

170 BPM stream practice! That's pretty much what Expert is. If you can make it through the first long stream, then you can do the second one. There's a really long break in the middle in case you need to catch your breath. Also, this chart has the most fun jumps that I have ever made. Hard is easy.
