KFX: Which cover solution do you prefer?

When converting to KFX which way of getting the cover do you use? And why? Adding amazon:XXXXXXX or just the isbn and reconnecting the kindle after amazon derps the covers?

Cheers :)

EDIT: I've been using amazon:XXXXXXX, mobi-asin:XXXXXXX but it sucks when azn pulls down a lame cover heh.
