I think my form is actually not that bad. But yet, when it starts to go I get nervous and probably make it worse until I don't feel like I have control and need to slow way down.
My bike is a Lemond carbon Zurich with a Ritchey carbon fork and Shimano wheels with DA hubs.
Lots of variables at work here.
As far as downhill technique, you want some weight on the pedals, some on the seat, some on the bars. In a corner, the outside pedal should be down and you should be leaning on it. Arms should be bent. Flap your elbows from time to time to make sure you stay loose.
Set your front tire pressure 5-10% lower than the rear and consider changing to a different size/brand of tires.
Sing as you go downhill, something upbeat you know well, out loud. It will help you relax into a rhythm and take your mind out of what you're doing. It sounds crazy, but I've been doing it for 20 years and I go downhill like a cannonball.
If a wobble starts, squeeze the top tube between your knees and slow with the rear brake only.
Good luck and let us know how it works out.
