I really need to get better answers to this question given my experience level. I'm sorry I don't have something for you now, but I'm not as confident in my ability to provide general advice as I am to give advice when I'm working one-on-on.

That said, I think my first pointer would be to ask your sub or switch friends you trust. Consensus from subs I've talked to is that (somewhat embarrassingly for my cohort, incl me!) other subs and switches who sub give better advice on this topic than the hypnotists most of the time.
