Major question (Choy Lay Fut)

Here’s a question I’ve had for quite some time. In some Choy Lay Fut schools they tell you that 5 wheel stance and 5 wheel fist are everything…very important. However in other Choy Lay Fut schools the 2 sets are not even mentioned. They sometimes start out with Small Plum Flower or whatever. Please answer for me! I need sleep!!!

What is the question?

The dragon reveals himself only to vanish

Where? Who?

There are many “pure” schools and many derivations. So where you are studying and who with is important for your question.
