Nuclear Hexagrams

Hello all,

Some of you know I'm still learning the Yi... and in that process I need to seek guidance and ask questions, etc.. Im very very sorry to annoy you guys with these questions, but I would really love to hear what you think on nuclear hexagrams.
How many of you read the nuclear hexagram? Do you read it in all your casts, or only in some?

Thanks a lot for your insights. :bows::bows::bows:

All the best,

B
