I just got my bike with Disc last month and I have already endoed but not downhill. I used to ride pull (v-brakes) and I liked them very well for my level (advanced beginner or low intermediate). I did like that they were super easy to adjust. I haven't rode the disc enough to become a full convert, DH immediately loved the change.
