I use Sadowsky's who have a tapered B available, but they are stainless....I'm happy with them. I also have Rotosound 77's on my ole Dean EAB that I actually like just fine as well. The Sadowskys are on the Warwick though.
The E is not tapered and black labels are medium+ gauge I'd say. The B is .135 for example.
Sorry, no help on the nickels.
Not much of an option for a 6 stringer though.
