Final shortcut over the wall
Take the mid-track turn extremely tight: quick left drift, release the mini-turbo, neutral charge jump off the top-left corner of the ramp over the rock, then trick off the strip of off-road onto the wall and back to the road. A regular mini-turbo trick off the ramp is the slower but easier fallback.
Wall-ride to rail section
On the top path, trick off the ramp onto the wall, ride it, auto-detach into an air trick onto the rail and right trick off at the tail of the boost; tricking onto the rail directly is the simpler fallback.
Start wall charge jump
At the very start, charge jump onto the wall instead of drifting the main road - an extremely easy, free time save.
Feather onto the glider path
Trick off the wall, hold left and feather up onto the glider path - faster, immune to shocks in play and safely above the pack. The best feather spot on the track.
