I realise that most of you are from the USA, but some while ago someone (either here or elsewhere) recommended Permajet Oyster 271 paper. This is available in the UK, but I do not know about USA availability. I use a Canon Pixma PRO-1 and they do not have ICC profiles for this on their website but I did my own, which give excellent results. In some respects, better than Canon Platinum, even though the Permajet Oyster is a satin and not a glossy paper. They have a free service to create a profile for any printer if required. They do have profiles for the Canon 9000 and 9500 though.
