I'm a huge fan of WC DH and 4x. Can't get enough of it. I used to do some dh and slalom but I mostly do All Mountain riding now. I like good singletrack that flows and is challenging. I love jumping too. I don't mind climbing at all. Shuttling is so much of a hassle that I don't think its worth it. Plus, the more you climb the easier it gets. I kinda feel sorry for guys who never pedal up. Your missing a lot of good riding and opportunities to improve your dh skills with improved fitness.
