JandCs ULF 400 film?

Has anyone out there used this "new updated version"?http://www.jandcphoto.com/index.asp?PageAction=VIEWPROD&ProdID=48 I'm looking for a faster speed in 11x14 for the obvious reasons.

I use that film often in 4x5 and 5x7, and I believe that it is only "updated" from a film made a few years ago that didn't have the density range of the current film. I don't believe it's been updated since.

It's a lot like the old TXT but with more modulated highlights, and it does very well in pyro.
