I hope I can word this correctly. If we are trying to balance our range and already have a very strong range does it matter if our opponents know when we are bluffing? In other words is their actual knowledge of our range change the fact of it being balanced? Or just the mere fact that we are mixing in something outside the norm makes it more balanced?

Hope this makes sense?
Your range is balanced only if your opponent is aware of it. It is not necessary to balance your range against an opp who only thinks about his cards and not yours: just value bet him. That's why it is often advised not to bluff at the micros: there is less need for balancing, since your opponents are less aware of your range.
