This thread's a few months old, but I found that the Enhanced Matte Neutral profile in QTR will work quite well on Bienfang 360 Translucent Marker paper. I just printed a step wedge that looks great, have not calibrated it, but shows a lot of promise.
I'm not saying it would make great negative material, since I havent tried that myself, but some prints may look absolutely beautiful on this paper. It was a favorite of many platinum printers and it is inexpensive...
