I've run into an interesting bug with the Gnarly binds - when I run around with Super Speed everything is fine, but when I stop Sprint turns on. I've tried both the 2.7 and 3.0 versions of the binds, and it keeps happening consistently. Sadly, I don't have enough magic to know how to remove Sprint from the binds - now that I have SS it's really not needed, and I really enjoy the on-demand feature.
