I'm not one that likes to bomb down a hill. I only descend because I have to get back down. I don't have any problems descending but just don't see the need to be bombing down for nuttin'. Every once in a while, I run into a Weisenheimer that brags about bombing down, then I'll let her rip just to see what he's got!
On a city street or residential area, I wouldn't do this!
