I got the set out and it is actually a deck with a book. The book has just the single card meanings and a number of spreads etc. I did not have a proper read at all and it is the first time I have really looked at it.
Rana George follows the French system. She has her own style based around it I believe. I saw one short demo she did and I did not mind it. The only time I ever saw her interact on another site she did not know the German or Brazilian systems. Not sure about now. That may have changed.
Andy B follows the German system.
Louis looks at traditional, core, and alternate meanings.
Looking at "Birds" it seems to follow the "German" and likely "Dutch" as that is a cross between systems. He even does the "Dondorf" meanings it seems. I think more so German actually.
Louis is one to read for sure. With Andy B you will see how harsh the cards can be not just the light side of it. He use to be on AT and was very strong about the way he saw the Lenormand and in a very "traditional" way.
I still prefer the French system.
