Kewl, thanks for the advice
I can play 11's now, but with my technique, it isn't easy.
I can pass Sepia on pad for example, and don't really have a problem doing longer songs.
I tend to have a physical barrier though stopping me from doing drills. Its not because I get tired. I can't do them full stop. My muscles lock up after the first couple.
An example would be Max 300 at the very end, where your meant to tap 3 times on your left then right foot. To get those, I have to use both my feet on the same arrow, as any more than 2 of those hits, and my muscles lock, not enabling me to do any more hits on that same foot at that speed. When alternating feet, I find it a bit easier.
I will attempt to flat foot though more
I have a Cobalt Flux that would make doing that rather easy, but then in our local arcade, we only have a DDR:X which is crap at FC's, and light button presses
