Cork vs Bio vs Flat

Trying to make a guide for all the tricks in the Park we try to really figure out the difference between cork, flat and bio. We have tried to make a model to see the differences without any grabs in there making it harder to analyze the movement. To compare we have put the model in a 540 version for all three of them. What we have figured out is as follows: (all for a left spinning person)

Flat: Spin, leaned back and leaned right
Cork: Spin, leaned back and leaned left
Bio: Spin: leaned forwardand leaned left

The third possible version seems not to be possible because leaning forward and right seems to cause a right rotation.

here are some pics of the models (most slightly off axis not extreme)

In how far is the idea we have behind cork, flat and bio correct? Is our description correct?

For switch jumps we had the idea that it just has to be the other way round,

flat: Spin leaned forward and left
cork: Spin leaned forward and right
bio: Spin leaned backward and right

Can that be correct?

here is a picture of a switch cork 5 model tryout

would be nice to get some feedback / ideas how we can make a good clear guide of what the differences are.
At the same time some advice for grabs fitting best together good with those spins would be great.

Thnx

your bio looks more like a misty and the flat has a bit too much flip but the corks are perfect man !

maybe make the jump a little bigger to have more spacing in betaen frames and you would have a pretty solid model

I think your definition of misty is off if you think that bio is a misty... Cause the bio diagram is literally just a guy leaning forward and spinning, never once do his feet go anywhere near his head. Versus a misty which is a flip straight over the head.

I do agree with a bigger jump for better spacing though, that would be nice, it could prevent confusion like this. Great thread OP.

Getting the basic off axis models done, what would be the most impotant grab combinations needed?
Which grabs should fit best which off axis spin so I can make some models of that as well?

isn't an underflip 180 to frontflip? sort of like an over inverted cork 5

Agree 100% with this. Your "bio" is like a textbook misty 5. I don't think bio 5 is an easy trick, 7's are much easier.

I think when taking a look at how the model is done the important thing with the underflip is that the model is facing the left side at the point where it is inverted. If I put the model in the position you describe it would be facing down the hill. The definition of underflip is making 180 turn (90+90 combined with lincoln loop) so actually it has to face sidewards when inverted. If I would have to do a guess what the move you describe could be I would maybe think that the position you get in would be more a d-spin.
Or beter let's put it this way, when I make the cork model being inverted I get into a position where the model is inverted facing down the hill.
Would be great to get feedback if that is true?

Then maybe this brings me to an important question on inverted versions:

with rodeo and misty, are the feet at some point directly over the head or is everything rodeo or misty where the feet go higher than the head?

To maybe make clear why I ask for how much invertion is needed, I want to basically figure out if there are key positions which are significant so that the model gets in there which would help not only to define the jump, but explain to others as well how it is done.

skis never go above the head in the photo sequence (that I see at least) = bio

sure it looks misty as they're both thrown forward into the jump, but if the feet stay below the head then it's a bio

tried to make a beter rodeo version.

what I find quite interesting is that to create the model I have to rotate the model 360 degrees backwards, while 180 spin.

with a flat the model is a rotation of 180 backwards and 360 spin,

could we maybe use that as a definition.

An significant position is that with this one the model changes the side where the upper body leans to from right to left in relation towards jump direction, which does not happen with a flatspin.

could this be a true definition for the difference?

This thread is awesome seriously, helped more than a lot
But I still can't make the difference between bios and flats. Sometimes, it's pretty obvious but not always. If the rotation is big (more than a 720), it's easy but under that, sometimes, I can't. A flat 5 looks the same to me as a bio 5 (I know they're not).
Does anyone know a way to see the difference? Cause the positions right before the take-off are really similar.
Thanks in advance for your answers

Could you do a D-spin and an overflip also?
