I agree with the general consensus - Downies, Amy, Claudia and then I am hoping Gabby can get back to something like full strength, I love her gymnastics, or possibly Ruby, who is such a fighter. I think Kelly will struggle on performance so far this year, although I like her, and it looks as though Catherine is not going to be ready.
However I also suspect they will go for Tunney and I am also not a fan - there's a scruffiness to her gymnastics and a general lack of performance.
Is it three count on each piece? I'd go:
Bars - Becky D, Claudia (?)
Beam - Becky D, Claudia, Amy (?)
Vault - Ellie , Claudia, Amy
Floor - Amy, Claudia, Ellie
Floor and vault are solid with the above. They need another bar worker and maybe beam. Catherine would have been perfect, Ruby or Gabby would be ok if they can work out beam, but Tunney might just have it on bar scores.
