Mirko has posted loads of information on this subject already in multiple threads. To sum up the new Adox MCC 111: it is basically the same emulsion from the late Agfa Classic, but with a whiter paper base. There have already been a couple of rounds of testing of this paper and the acclaim from APUG users has been almost universally positive. Mirko has said that Freestyle will be handling distribution of this paper in the States.
As far as warmtone papers go, there's Kentmere's Fineprint WT (semi-matte only...no glossy), Kentona, Fomatone FB WT, Fomatone WT Chamois, Oriental VC WT, Ilford FB WT and Fotospeed Lith. I personally love Kentona, but it's a graded paper (about US #2.5) and thus not an all-purpose item. Fotospeed Lith I believe has the same paper base as Kentona, but a different emulsion. Foma's warm tones have always been a bit much for me--the chamois paper especially (pricey, too!). Kentmere's also a bit warmer than Forte was...I suppose the closest candidates would probably be Ilford and Oriental. Mind you, that's not saying that either displays properties that are really close to Forte's...there are definite differences. Perhaps an alternative might be to take a good neutral paper and use warmtone developer. Or you could of course just tone the print to make it as warm as you want.
