Hey all.

I am finally about to take the plunge into the Hellboy universe. I've got Hellboy trades 1-6 and BPRD Plague of Frogs 1-4 coming. I've already read Hellboy 1-2 since I borrowed my friend's Library Edition.

Question is: Should I read all of the Hellboy trades up to 6 before jumping over to BPRD for Plague of Frogs? Or do I need to continue onto Hellboy 7+ before Plague of Frogs?
