Frankly I am torn between Yuna. Gracie and Julia. Julia may have a lot of pressure on her to shine but than so does Yuna to repeat. This is the Olympics so anything can happen but I predict that Gracie will impress even if she does not win gold.
Gracie has already impressed me. She has a lot to work on not unlike the rest of the youngsters but she is coming along quite nicely. She's America's #1 for some time to come. I could watch her spins all day long.
