Wheel cover - but which one?

I’m looking to get an aero wheel cover from wheelbuilder.com. Question is for which wheel? Up until now I have trained and raced on a set of Carbones. I recently acquired a PT on an Aerohead rim. Race distances for next year will include a couple of olys and a half. Any suggestions ST? Thanks in advance.

on the pt rim.

Thanks. I was leaning that way by assuming that I would race with the PT but reluctant to take the Carbone out of the line up because they look way cooler :slight_smile:
