I have V1 down and my V2 is getting better. I have not yet tried any "Snorkelling with fishes." Is that some sort of new uphill stride or perhaps shorthand for skiing through deep snow?
It's a technique for when the powder is so deep you can't stick your head out the top. Fishes are what we call Texans that don't know said technique.
Obviously this must be a variation of the well-known "herring bone" technique...
Oh. :-( I'm a fish. Sadness.
It's ok. We'll train you over xmas. There is much snow.
