I used Epson luster paper for years,but lately I've been using Ilford Smooth Pearl Paper,for my everyday paper.
A big +1, on the Canson Platine...{my favorite }...a really fine paper, with a great feel ,and deep blacks.
Another one you might want to consider is,Harman by Hahnemuhle Gloss Art Fibre.
Hope this helps,
Mike
