I don't know if I'm going to be able to find the clip again, but there was an interview with Jordan Chiles this weekend about her training progress, and she indicated that she's going for an Amanar and Cheng as her vaults for this upcoming season. Throwing her name into the Carey/Roberson race while also maintaining her position in the solid AA race with DiCello/Wong is a good strategy IMO and could open the door for someone like Zoe Miller, since Chiles would be able to do more heavy lifting in team finals than Carey/Roberson.
It has that awful AI voice over but it includes the part where she is talking about her vault upgrades.
