I think I answered my own question - B&H no longer lists the Fiber variety and Oriental USA has not answered my inquiry in over a month. Too bad; I liked the paper very much.
Great paper I hope it's coming back - Adox stopped it's MC110 fiber base paper at the same time. Might be due to the same supplier of it's base component charging astronomical prices now. See the Adox site. http://www.adox.de/Photo/mcc-and-mcp-production-situation/
