If I can’t use my LL chip in Spa, which race would be the next best?

If everything goes well this weekend, I will be able to get a PIA, RUS, MCL, MER lineup on my first team for Spa. However, since changes made before LL is applied aren’t saved, I won’t be able to use the chip in Spa unless I take the risk and wait to add George until after (which is an option, I’m just wary of taking it). Is there a race where LL would still be a strong option?
