I'm looking for paper to make giclee prints with my Canon image PROGRAF PRO-300. The ones that have worked best for me so far have been the Fluid 100 series Hot Press Finish (8x8 in, 300 g/m2) by Global Art, Materials, Inc. These get the ink in a super-accurate way with excellent contrast. I recently tried the Arches watercolor hot pressed (20×20 cm, 300 g/m2), which grabs the ink with higher precision but sucks the ink so that all colors fade and blacks aren't as dark.
