Steering Dampener?

[Bobbyhotrods@comcast.net]

List, I'm assuming I don't need a steering dampener on my street roadster. It 
has mucho caster at 15 degrees. It's a traditional Ford pickup box -drag link, 
straight axle, buggy sprung deal. 
I can't imagine a scenario where the front end would start doing the "Frisbie 
Flops" that I've encountered on the street with an undampened car......Thanks,
