I flipped mine due to inexperience -- I entered a corner too steep and then did a couple quick overcorrections that sealed my fate. Having had a chance to improve my riding skills, I can go much faster on much more difficult roads without trouble. A tadpole is a total blast to take down a steep descent with lots of hairpin turns.

Although tadpoles are great at lower speeds, I think that racing bikes handle better and feel more secure at high speeds. Much easier to do heavy braking or control a crash.
