I just notices that the 3rd post in this thread has a COUNTER-ROTATION 180 video that describes it. Unfortunately, no one including me noticed it was there.
And I thought the OP asked about BEGINNER 180's. Why are you bringing 100 foot 180's and 360's up? Something wrong with doing a 180 on flat ground or 1 inch box first???
You're digging a hole here. You CAN counter-rotate a 180 off a jump, the problem is you don't want to and shouldn't be doing it that way off jumps in 99 out of 100 cases.
I watched the whole video to be sure, but as I suspected, the SA video even says that counter-rotated 180s are used mainly on rails and boxes to stop rotation at 180 and 180 back out.
Also it says counter-rotated 180s are an ADVANCED technique. You should not be doing that right away, particularly off jumps.
If you knew park progression you'd know that you almost always want to use rotation, not counter-rotation to spin a 180 off a jump.
It's very rare, specific circumstances when you'll be using counter-rotation for a 180 on a jump because every single park rider will tell you it's way more stable to use rotation, not counter-rotation for 180s off jumps.
This is exactly why you shouldn't be giving park advice. You don't have the skillset and progression in the park to draw your advice from. You're mainly guessing without knowing how progression works.
On this note, getting tired of people pointing me to SA videos to prove a point that's wrong. Trust me, I know Nev personally and he isn't teaching people to counter-rotate their 180s off jumps when they're starting out in the park.
