I'll probably get some groans from the Peanut Gallery for suggesting this, but try a pack of Merkur blades. I've heard there can be serious QA problems with them, but every pack I've ever had the razors were awesome, and when Merkurs are on, they are ON.
I use them in my '60 Flair-Tip SS, and get BBS most of the time.
I don't think the Merkurs are crazy talk at all. It's been my favorite so far.
