I'm wondering how Carcass is not a headliner though. Even though they did those two reunion tours they would still be a big draw. Maybe they have even bigger bands up their sleeves? King Diamond seems like a logical choice. But anyway... seeing Carcass playing a short set would kind of suck, unless you weren't that familiar with them. When they play short sets they mainly focus on Heartwork, and while I think it's a great album, I'd rather have some more early stuff.
