AS1, please!
And I think WE1 right after KY2 is a bit boring, since they both have long straights and heavily favour the XRG. Maybe you could switch it up a bit like: SO4 | KY2 | FE2 | WE1 | SO3r
Same for KY3r and AS3.
It would add a bit of diversity, IMO.
Oh, and SO2 and SO3 could be a problem when the server gets its deserved popularity because of the 16-car-limit.
