always more drops, jumps and skinnies. as for beginners, there's always the option of making bail routes around features. or more accurately, an xc course with feature options. also safer roll-over-able jumps. the big gap at the bottom of the right big sister run could be made into a table top so the penalty for coming up short isn't so severe, yet those who can gap it can still get sufficiently rad. involves a lot of digging.
