I rode Mammoth Kamikaze back in the early 90's on a renta bike. Scary thing about the US bikes is the reverse brake setup, kinda scary entering a hairpin at 90kmh, bike shuddering on the braking bumps and you're unsure which end is about to lock up. If you overshoot, you will likely land about 150m down the slope on your first bounce.
Not my fave trail but I do like to brag!
