Digital BW, The Print

Today I have buyed a pack of Arches paper (Natural Soft grain satiné 
and Natural Textured grain fin). I'm printing on Epson 2400 using OEM 
driver (B&W Advanced mode). From their website at www.arches-papers.com 
I have downloaded some inkjet profiles adapted for Epson 2100. They say 
specifically made for Ultrachrome. But taking into account the inks 
changes from first Ultrachrome (2 blacks/grey if I remember) to latest 
K3, is there any new profile adapted to 2400 and K3 inks?
Have you used this paper, and does anyone have any special 
recomendation?

Thanks a lot for your help.
