Fomalux 312 falls into the same category, right? (Except for being RC rather than FB---but it's a chloride paper that Foma describe as "contact speed", which I assume means "in the same league as Azo and Lodima".) That's what I've been using to avoid the unreasonably short times with enlarging paper---with a 7.5W bulb, usually a bit over a metre from the negative, a typical exposure time is a minute or a little less.

I have no real idea how *good* the Foma paper is---I don't think I have a developed enough eye yet for paper nuances---but it's cheap, convenient, and slow.
