I think I have to go with ILTB here. It's one thing to know your equipment inside out and know all your braking and balance points. It's another to suggest that this knowledge will prevent you from ever dumping the bike over forwards.
I've practiced stoppies and endos for years, and had a spectacular and largely unintentional 25mph-to-zero nose-wheelie on my road bike the other month when a box truck made a quick lane change. But given the right combination of inopportune circumstances, there's a pretty good chance I could still go over the bars.
Less likely perhaps, at best.
