Given the reports that Ellie is still struggling with her triples, especially the throws, I'm going with Chan/Howe and three new teams - two of whom haven't even made their competitive debuts - McBeath/Parkman, Efimova/Mitrofanov and Scott/Siianytsia. I'm sure I'll be wrong about at least one of these teams, but this is my guess and I'm stickin' to it for at least 2 more weeks until the Boston Open, lol.
