Well...might the introduction of Cooltone in FB drive a demand for it? You do have a "matching" WT developer for the WT paper (which I use, and it's excellent with your paper.)

The only thing that kept me from trying Cooltone RC paper was that it was not available in 16x20 so I didn't want to get addicted to a paper I couldn't get for my largest prints. With the FB being available in 16x20 (and even 20x24 though that's currently irrelevant for me) that's changed and I'll be trying out some of the Cooltone FB.
