So I'm comfortably rolled for 200nl after a good month and I'm going to be moving up by next month. What can I expect the differences to be from 100nl. I heard this is the hardest jump, is that true?

I expect to get 3 bet more frequently, anything else?
Is there a list of regs I should avoid before I'm comfortable with the stakes?

(It will be stars 200nl btw)

Thanks.
