I used to love downhill, though not quite on the same scale as that video! Im very much a novice, and when I finally spashed out on a good bike I went for a Marin trail bike. Its a great jack-of-all-trades bike but I sometimes regret not getting the Scott DH bike that was also for sale at the time, for cheaper.
Not many tracks around my way, only one I know of is called Brechfa and its not very challenging (well, maybe on youre endurance - 2 massive hills to climb).
