I think Simone, Skye, Shi, and Leanne are locks at this point. The only question I'd feel the need to answer at camp is who goes with them. Those four make up 3 of the top 4 on every apparatus, so it's honestly not very critical. They are the top 4 on bars, so I wouldn't bother with a bar specialist at all. Joscelyn finished second on vault, Suni 3rd on beam, and Kaliya 2nd on floor.
Suni only outscored Shi by .1 over the two days on beam and Shi had the higher top score, so I think Suni would have to blow it away at camp to be chosen. If her health keeps improving, I think she can be right back in it next year, though.
Kaliya was a full point better than Leanne on floor on night 1 and only 0.050 night two, so she's an improvement but it depends on the day how much. However, Skye absolutely cannot be used on floor, so I think that gives Kaliya a bit of an edge.
Joscelyn was .3 better than Skye on vault each night. Joscelyn finished higher than Kaliya for AA. That being said, if we had to count Leanne's score on vault, it's not a big disaster.
Basically Joscelyn has the highest contribution overall, but Kaliya's best even is an event where we don't already have four good scores. I think it's between these two and no one else at camp unless Suni looks great.
