I would strongly recommend a custom profile. With one for my 9800 I have a 30% gamut increase over the canned profile. I use Relative Colorimetric rendering and the Premium SemiGloss setting for the printer.
From memory the Crane profile uses Perceptual and PSG.Black point on. 1440 is fine with this paper
