Yarr, I need to give you the Touhou Project, and I'll show you some incredible 13 footers. The lowest in the pack is one 10 footer (besides a 1 footer that should be an 11 or 12) and the highest is a 15 footer (which should also be like a 12). There are plenty of 12-14 footers in it, and if that isn't enough, it's got tons of great songs.
Strangeprogram tends to annoy me, but hey, it's one of the more annoying Sharpnel songs out there.
And I take it you play spread? I play a strange take on spread. x3
S = Left, left index finger
L = Down, right index finger
E = Up, left middle finger
P = Right, right middle finger
And time for another nonimpressive score, but it's (don't laugh) my first AA on a 13 footer:
