What are some good figures for avoidance in Bronze American Style Smooth? Particularly waltz and foxtrot please. Thank you!

Maybe if you explained your question a little more, then you would get a few answers. I would think that as you work your way through the bronze syllabus you would start feeling very comfortable with the steps/figures at each stage. But, I don't see any reason to "avoid" any of them unless you are uncomfortable with the execution of a particular step. In such a case, it would take additional practice to ensure that you can execute the step properly. As the execution becomes more natural, then the step becomes more comfortable. It will vary from dancer to dancer.
