Fire Field Cylinder Knot
Like most people I don't play this course much, oddly I think its a good course but just so much jank you have to control that it feels like you're getting beat up. Something I was informed of is that on the big knot holding up on the joystick gives you a better chance at the shift boost, some hidden shift boost are like that.
Back in the early days of snaking I was the first player to get sub 2min on FFCK.

I haven't spent too much time on this course overall, my biggest weakness is getting 1st lap shift boosts in the tunnel, once you can master that technique then you can get some really good times.

This run with Iron Tiger is my favorite run I've done on CPDB and its back in the day when I recorded replays with pilot theme songs.
I'm using Omega Condor-V2 here so I was being serious about setting the fastest time possible and was able to get sub 1'50 after being stuck getting 1'50's countless times.
CPDB ending section has possibilities for explosive finishes and who knows if one could be a super finish going twice as fast as this.
Lightning Half Pipe
King Neptune is a custom machine I mained for a while because I really like its feel and it has a cool name, its one of the best special named custom machines in the game.
Another ancient snaking run which was a big deal at the time when I set it because LHP was not a course that got any serious snaking play on it from the community.

My run with Death Anchor is one of the last remaining times set in the early era that hasn't been beaten yet on the Max Speed no side attacks spreadsheet, I did this run in 2004 and somehow its still holds up.
Even though my current pb is 1'43"911 with Omega Condor-V2 my favorite snaking run is with Dark Schneider. Once I get sub 1'40 then maybe I'll have a new favorite run.
BBO is the easiest course to do spaceflying since the flight path is simple with visual indicators of where you need to be to make the laps count. Other spaceflying runs require complicated flight patterns and advanced techniques such as wall clip outs and getting the finish line lap glitch.
