I am getting a Rush 400
Getting back to the original point on the Rush or Prophit, I ran into the same dilema. Rush is faster more tuned in for XC while to prophit will alow you to hang on the bigger stuff drops and freeriding but will not climb like a good xc.. But before I tell you my decion, I have to tell you why.. I cracked my Jekal frame and instead of getting a new frame Cannondale offered me the Rush for cost.. I really wanted the Prophit to hang on drops and side tricks, but the dealer told me if I take the lower end profit (same price as the lower end rush) they will charge me an extra $800.. So I re read my reviews and choose the Rush. I weigh about 200lb and ride very hard, I figure that since I still have the components of my jekal I can slip them on the rush as they wear out. I can't do that with The Prophit.. But if I was in your place I would ask myslef this "Do I avoid the big drops, the fast downhills and log roller" if your answer is "yes" take the rush, at least you can still hit that shit and go fast. But At least get the 1000!
