Lemon OG Kush was nice, although the lemon taste wasn't as pronounced as I'd hoped (in my pheno at least...I've only grown one seed out) it certainly has that fuel "under"tone though.
I do remember original NYC Diesel having a really fruity (grapefruit) punch when I first tried it in Dam 10 years ago. Not sure if that's still the case or if the diesel taste has taken over.
