So I messed around with riding straight to the rail versus a corkscrew approach to keep that metabolic burn low (with the corkscrew) and I'm not sure I ever saw a difference in resulting 200m times. Granted, the ride to the rail on the back straight was assisted by a BIG push from my holder. Watching world cup quals, I feel like even on steep tracks the bias is towards going straight to the rail. It's probably easier to pull off a ride to the rail at Major Taylor than say, Rock Hill or LA.
