Yeah, I know what you mean. I didn't put up a pic to compare their heat pits either. You can't really see it in the pic because I didn't get a good angle but Slim also has a more squared head, a lot wider than Freddie's is. It's like Freddie is a Civic and Slim is a Corvette (Fender shape comparison to heat pits and head shape lol). It's too hot here, forgive me XD
