It sounds like you are pretty clean already. Here's the good news and the bad news: You may not have any ropes / MP. If you purchase more products with the intention of releasing those, you may be wasting your money.
Now on the other hand, I read a RAW website(www.shazzie.com/raw/articles/mucoid.shtml) in which shazzie, who is on a raw foods diet, just one day up and released a ton of MP. A doctor told me once, "the body has it's own timing for things, when it is ready it will come out". I think this applies here, if you stay on a healthy Diet and cleanse gently I bet if you do have MP it will come out on it's own.
Some of us with less healthy diets or impaction need products, you may not need them. Or maybe, they already worked for you and you didn't notice the MP in the bowl movement.
