I'd say the two pickups you've narrowed it down to are very similar. They respond to high gain with added fuzz IMHO. As I was playing through the FS7 I was thinking of my experience with the EVO6. I couldn't get a good clear note no matter how I adjusted anything. But obviously many others have had success with them.
As I mentioned before, if you want the FS7, I have a barely used one available - $70 shipped? PM me if you're interested.
