The aim of this thread is to define the spin direction of various tricks that, when performed with only one hand, spin clockwise with their Normal variation, and counter-clockwise with their Reverse, and the opposite with the other hand; but that have a no clear spin direction when performed CW or CCW with both hands.
This video will help to understand the idea:
I'm going to analize the tricks. Keep in mind that I'm left-handed:
1- IndexThumb'Around - In this trick, the pen goes around the left Index finger and the right Thumb. Done in that way we have an Indexaround Normal plus a Thumbaround Reverse done at the same time.
2- Charge 11' - It's basically a Charge done with both Index fingers. For the left hand is a Charge Normal and for the right a Charge Reverse.
3- Shadow 11'-11' - Ditto with a Shadow.
4- FL ThumbThumb'Around - Similar to the first trick: for the left hand we do a FL TA Rev and for the right a FL TA Nor.
5- ThumbIndexIndex'Spin - A ThumbIndexspin Reverse for the left hand plus an Indexspin Normal for the right.
6- Triangle Pass T1T' - For the left hand this is a Triangle Pass Normal, for the right is Reverse.
7- Wiper 11' - This Wiper is special because can do whole rotations. In this case I think the Wiper is Normal for both hands, but these have an uncommon position.
So we basically have two groups, excluding the Wiper:
Tricks that spin on a horizontal plain - Tricks 2, 3, 4, 5 and 6. The spin direction for these tricks could be described with CW and CCW, because we assume that the point of view will be from above (no one will look at a Triangle Pass from below).
Tricks that spin on a vertical or diagonal plain - Trick 1, we could find more. We can not describe these tricks with CW and CCW, because people can see it from different points of view, causing they to see the tricks spin CW or CCW depending on where they are.
Should we find a new description for the spin direction of these tricks?
Assigning them a spin direction (Normal or Reverse) could be confusing. Take the Triangle Pass T1T' on the video as example: if we say that is a Triangle Pass Normal, doing Triangle Pass Normal T12 > Triangle Pass Normal T1T' > Triangle Pass Reverse T'1'2' would mean that we change the direction, but it isn't really changing! -

Basically, any trick you can do in one hand, you can do in two. Sonics, shadows, backarounds, charges, whatever.
This could be better fixed with a developed two-handed spinning notation. Which was supposed to be released sometime ago... -

I would say that the direction should follow the prime hand or the hand beginning the trick for charges and shadows it should follow the prime hand, for the arounds it should be the same as the starting hand

the two handed spinning notation is simply about fingers and its already being used in this video, it says nothing about spin direction
the easiest imo is to set an arbitrary convention. like we fix it to be always from the perspective of the right hand, regardless wihch hand in dominant. -

Pretty biased?? And wouldn't it get complicated when you write a combo involving this stuff for lefties?? -

we are talking abt 2h tricks... hand dominance means nothing if ur using both of them at the same time! -

I just don't think spin direction is a necessary complication when there isn't even a set two-handed notation. -

he means the informal 12345678 notation i made that no one ever wrote an article for xD i probably should but im not sure how...
i think.

whether you use ' or Y5678, it has nothing to do with spin direction, completely orthogonal issues
