Sounds great. I admire your persistence. Like Mike said, it's already plenty fast to sound good. I think as pickers it's easy to get obsessed with gaining maxmum speed, when casual listeners aren't going to tell the difference between 235 bpm and 275 bpm -either way sounds fast to them.
I do, however, understand your need for speed. I hadn't tried playing FMB with the .tef file in months, but this thread got me wondering if I could reach 100%, now. Sadly, the answer is still no, but I'll keep trying.
