FWIW, I use IP 9 with a calibrated NEC MultiSync PA271W and 3880, have been since version 6, and couldn't be happier. I've settled on the Epson Hot Press Natural for my B&W, often converting to grayscale for my higher contrast images. The blacks are the best I've found, deep and rich with as much detail as I add during processing.
For my glossy, I've found that Canson Baryta paper is producing exactly what I am seeing on my monitor.
These results are better than what I've gotten with any of the Hahnemuhle papers that I've tried including Photo Rag, William Turner and their Baryta line. I've also tried Pictorico for glossy and of course most of the Epson papers.
If price isn't a obstacle, I would recommend it, keeping in mind that upgrades, both to versions and for changing printers can be pricy.
