Stupid fingers

After many, many hours spent in front of the TV playing Guitar Hero 2, I can state with some authority that I believe pull offs are impossible to do. This may just be because I have stupid fingers, but I believe it being impossible for anyone is more likely. I can do the hammer ons with pretty good precision at this point, but I just can’t convince my fingers to do the opposite motion. I don’t suppose anyone has any suggestions for mastering this.

If I could figure this out, I’d be a whole lot better at the game. I can strum pretty quickly, though not quite fast enough yet to play through Misrilou on expert. That’s going to take a lot of work, but it’s doable. And I can get through songs like YYZ on hard with some competency as well as do a lot of the chord stuff. It’s just that moving back and forth on the fret buttons that I can’t figure out yet. But once I do, I figure I will be unstoppable.
