there's no "corkscrew" @ TH.
there is "the cyclone". it's turn 5, and is the "signature" turn of the track, just like the corkscrew is for LSIR.
there is also a bypass configuration, which eliminates going up and over the cyclone.
I can't speak for ViperDays though I believe in the past the full track config was used (no bypass).
personally, I find the bypass Much less fun than the cyclone, besides being much scarier. the bypass creates a 'weirded out blind braking' zone before going quite off camber. whereas the cyclcone is just an awesome rush everytime.
