Well, I'm not familiar with this roads but regardless if it has a bike lane, paved shoulder or a wide outer lane, either way is ok. If I had to take the lane, then I would prefer to avoid using that road if possible.
There's one road like you seem to describe where I live, 2 lanes on each side, narrow lanes and a curb to the side so one must take the lane, traffic is fast with medium to heavy density. It is not the end of the world to use it, no big deal overall really. However, the main objection is that doing so greatly reduces my "fun" of riding, and fun is the main reason I prefer to get around using a bicycle. So I think of it as a "bad" or "unfreindly" road.
