I got him with 2 BRs, yes. Turbo up to the skillcut, 1st BR there, then drop down to the left with sideshift after the last speedpad on the skillcut, BR No.2 on the drop, catch another speedpad on the landing.
EDIT: yay 3000th post, thanks for pointing it out KIGO. Now, where's my trophy?
...
yes, turbo onto the narrow bridge. hit the turbo as soon as your ship is around the inner apex of the lefthander before the jump, then pull up and BR, and try to land before the first speedpad on the bridge. After the last speedpad on the bridge, sideshift left (without turning) and BR, you should land right on the banking of the lower track, get the BR boost, then drop off to the left onto the right speedpad.
It is also worth mentioning that I didn't use a single airbrake for that line, only sideshifting. I also used sideshift to catch the 3 diagonal speedpads on the straight after the first lefthander - no turning of the craft required.
