QTR-Quadtone RIP

I've been printing with Moab Entrada Natural for years with QTR and have liked the results. I'm now trying to see if glossy paper is all it's cracked up to be, eg better tonal range and definitely better Dmax. With my Epson 3880 and Mac Pro the glossy papers that show up are not well identified. I have some Ilford Smooth Pearl, beloved by my favorite color printer, Charles Cramer, and some Canson Platine Silver Rag. I like the way they print in color but would like to use them with QTR as well.

What is "Ilford Smooth," is it smooth pearl, or smooth something else?

Of the listed papers, what is closest to the ones I've listed? I'm not quite prepared to make my own profiles, I do not have a spectrophotometer.

Thanks for any help.
