The problem with the whole notion of testing papers using an image first, is that there may or may not be limitations to each of the profiles. These profiles will be different in their gamuts and cutoff points.
In my website at
www.dygartphotography.com, in the technical section, you will find a method for testing how the paper responds to ink in an objective and comparative method that makes no use of profiles. It enables direct comparisons based on ramps divided into 5% increments of each ink, from 5 to 100%. The densities are then plotted and compared. The only variable is the type of ink used for black, as appropriate for the paper (matte or glossy), and the dots per inch setting, so you can standardize or retest with different dpi settings. I've tested a number of papers that way on my Epson 3800, keeping everything as standardized as possible. More results will be posted shortly.
After you have determined how each paper takes ink without the influence of profiles or other quality adjustments, and compare the results, you will have far fewer papers to test with images, but at that point you definitely should do that. Regardless of your density plots, other factors, such as curling, bronzing, metameric effects, lighting and surface reflection, the results of profiling, and your visual requirements and preferences, will help to further refine your selections. It's good that we have so many choices out there, but it does help to narrow them down in a scientific manner before simply deciding that you like or don't like them. The other thing to do is to check the testing agencies, such as Aardenberg and Wilhelm, to see whether a specific paper and ink combination can be expected to have good image longevity or not.
