I've just got to say, I don't think I've heard the word "bobo" in 25 years.

Now, in an effort to contribute something useful to the thread, maybe it's the disconnect between the little I know about various flavors of mountain biking and the almost nothing I know about BMX, but it really doesn't seem to me like "jumps" and "rigid" belong together.

Also, you should check out cyclocross racing. There's a guy around here who did our big CX race series on a BMX bike last year. He was definitely a crowd favorite.
