hey im wanting too spend some serious dollars on a dh race bike cuz i want too do some dh races. i went to wc and now im amped. im a fairly good rider and want a bike i can really feel working underneath me aswell as being stable predictabl solid etc. im looking at a norco team 07 and 08. and a kona stab supreme 08 model and maybe a giant glory1. some people say the giant is such a fast bike but i like the feel of the kona when i sat on it but being a more visually less complicated bike im not sure how well they work. does the kona rail corners and is it rediculously responsive and easy to throw around. norco what about these.
