If I have someone within the team that can keep Kimi interested & motivated - then Kimi.
If I need a second driver to contribute points to help get the constructors title - then Button.
If I'm looking for some flash & headlines to attract some specific sponsors - then Kimi.
If I'm looking to widen my team's support in the UK - then Button.
so...ummm....what's the criteria we're basing this on again?
