The proper balance is going to depend on your opponent's tendencies. Unless both opponents play Game Theory Optimal, there isn't a single correct answer (and even if they both are, we don't know that answer yet!)
If you continuation bet the range that you stated, and your opponent starts check/raising a lot, you can adjust by calling those check/raises with a wider range, including any pair. You would also want to reduce your continuation betting of hands that could draw to a decent hand, but are current useless. For instance, start checking behind stronger broadway hands that could make a best hand with 2nd pair, or pocket pairs that are somewhere between the top and bottom cards on the flop, while leaving some trash like 54s and 65s that didn't connect in your c-betting range. This will nearly polarize your range - if you divided your range into 4 sections, you would cbet the top 40% and bottom 20% of your range. If you get played back at, you can continue with the most of the top of your range, while tossing the trash.
