The videos where both obtained from Turtle Spin. Reverse Shadow Still and Neobak 12-12. What is the difference between them?

Firstly I'm sorry if I offended you in the other topics... I just wanted to appraise you of the rules, since I admit they aren't perfectly clear... I guess I wasn't either.

On Topic: The difference is basically that the neobak is done fingerlessly, while the shadow uses a finger push. You could say FL Shadow Reverse 12-12 = Neobak 12-12. Hope that helps!

Oh...I didn´t looked at the specific details. Now I understand. Done.
Well, then if I wanna know if "Fingerless ThumbAround Reverse" and "Fingerless ThumbAround Harmonic" exists, should I post here, or make a new Topic, at Advanced Tricks forum, or another?

eh, you could make a new topic if you wanted, but I'll just anwser it... they both exist and are not very difficult.

Another main difference is that the reverse shadow has 1.5 spins whereas the neobak 12-12 only has 1.

? neobak has 1.5 spins too.. just closer to the knuckles

Ah..Okey, then there are two differences. Well, normally I do a spin of 1.5 at shadow, but is it possible to do a Shadow with 1 spin? (If it exists, then it must be a variation: give me the name)
Another thing: is there a NeoBak Reverse?
NeoBak is aviable to do in other fingers, right? 23-23 and 24-24? Or it isn´t possible?
Hmm.. I have seen topics that have title as Difference between TumbSpin and Thumb Around. Well, I have read, but still dont understand. Any explanation should be great!
@firebird: Oh, yeah, I didn´t noticed that difference.
@katto: NeoBak has one (1) spin only. You can watch the video from Turtle Spin web page.

Neobaks can start in any slot and can also travel down the hand (normal) or up the hand (reverse). Examples below:

Neobak Normal 12-12
Neobak Normal 12-23
Neobak Normal 12-34
Neobak Normal 23-23
Neobak Normal 23-34
Neobak Normal 34-34

Neobak Reverse 34-34
Neobak Reverse 34-23
Neobak Reverse 34-12
Neobak Reverse 23-23
Neobak Reverse 23-12
Neobak Reverse 12-12

The default Neobak has a minimum amount of 1.5 rotations. The Neobak Fall combo only uses incomplete Neobaks. Instead of catching the pen and doing the last 0.5 rotation, you substitute the catch of the first 2 Neobaks with the under-the-finger move to bring the pen down a slot.

For more info on Neobackarounds, read the Neobackaround Normal Thread.

For more info on Shadows, read the Shadow Normal Thread.

Hmm... Do you mean that a Neobak Normal cannont spin 23-12?
Another questions regarding to tricks:
1. Is 360 degree the same as a ThumbAround?
2. Is ThumbAround the same as Thumb Spin?
3. @sketching: if you say that it has a 1.5 spin, why in TurtleSpin web page appears with only 1.0 spin? Is the trick done incorrectly? (At that Web Page)
4. Is a Devil´s Sonic the same as a Devil´s Spin?
5. A Double is a Forward 2.0? A Triple then is a Forward 3.0? Or we don´t say Forward 2.0 nor 3.0, and only say Double - Triple?
6. Is a Double Charge the same as a Twisted Sonic, extending with another Sonic?
7. A MidBak is a BakAround between 23?
8. I am confused after reading topics of BakArounds. What is a Korean BakAround and a (English, I suppose) BakAround? A Kam´s BakAround belongs to Korean, or to English Community accepted BakAround?
9. What do Korean´s BakAround differs from English Community accepted BakAround?
(For not been posting a lot of topics to separate each of them)

1) yeah but no one calls it a 360 degree
2) TS is on top of the thumb TA is around
3) the push 0.5 spin 0.5 catch 0.5
4) devils sonic is 23-12 spin(around) is 23-23
5) fake double isnt a TS 2.0 it just looks kind of like one
6) double charge is tw sonic > warped sonic
7) yes
8) ucpsb and kam likes to do their backarounds closer to the knuckles like it's supposed to be, but korean do it closer to the tips.
9) ^

A thumbaround has exactly 1 spin. A thumbspin involves the same push and catch, but does at least 1.5 spins on top of the thumb.

I didn´t say Fake Double, just Double.

Double TA is a combo of TA -> FingerLess TA.
Triple would be TA -> FL TA -> FL TA.

TS 2.0 is a ThumbSpin with 2 rotations. The old name for this is "Forward 2.0," but this name is outdated.

2. Is ThumbAround the same as Thumb Spin?
---- Thumbspin just means that the pen spins on the Thumb. It can be anything from 0.5 to X.X rotations as long as they are on the Thumb.

3. @sketching: if you say that it has a 1.5 spin, why in TurtleSpin web page appears with only 1.0 spin? Is the trick done incorrectly? (At that Web Page)
---- The video for the Neobak 12-12 is incomplete, the catch is done properly. Look at the videos for 23-23 and 34-34, they have the full catch. 1.5 rotations total.

4. Is a Devil´s Sonic the same as a Devil´s Spin?
---- Devil's Spin is an old name for Devil's Around.

5. A Double is a Forward 2.0? A Triple then is a Forward 3.0? Or we don´t say Forward 2.0 nor 3.0, and only say Double - Triple?
---- Double jsut means 2 rotations. Don't try naming new combos with Double or Triple, etc... that's more of an old-school way of naming things that doesn't make as much sense anymore.

6. Is a Double Charge the same as a Twisted Sonic, extending with another Sonic?
---- Double Charge only refers to: Twisted Sonic > Pass. Not Twisted Sonic > Warped Sonic. That would have too many Charges.

7. A MidBak is a BakAround between 23?
---- A Middlebak is a Backaround that begins and ends in the 23 slot, without going through the T1 slot. A Backaround 23 does not have to end anywhere in particular. I still want Backarounds to go through the T1 slot, but I'm apparently in the minority on that point. <_<

8. I am confused after reading topics of BakArounds. What is a Korean BakAround and a (English, I suppose) BakAround? A Kam´s BakAround belongs to Korean, or to English Community accepted BakAround?
---- Korean Backaround is a Fingerless Indexaround Reverse. Someone apparently felt sorry that the Koreans got the trick wrong and called it "Korean Backaround." Watch David Weis to see how Backaround should be done. He invented them, afterwall.

Well, as Katto d(^.^)z said, then Korean BakAround must be close to the tips, and not as us (The UCPSB), close to the knuckles.

Due to question number 5, what is Forward actually called?

Forward = Thumbaround Normal
Reverse = Thumbaround Reverse

Fake Reverse is named because, when it was named, it looked like a TA Rev (Reverse).

You will also see references by David Weis to a Forward 1.5, that would be a Thumbspin 1.5.
