A rhythm line of progressively larger step ups/tables is great, Stowe had a nice three/four jump rhythm line last year in the med park. Railswise I like street style down rails, and big tabletop takeoff style flat down boxes. I also like the creative features, something that might not flow in a slopestyle line but is great for an individual session, or last hit in the park examples are wall rides or stall bars. A huge step down can be pretty intimidating at first but is always a thrill once you get it dialed.
