Liquidol paper dev, easy to mix, lasts forever (a couple printing sessions if the nber of prints are low per session), ships free from Amazon.
Slavich Unibrom, graded, single weight, fiber, matte, smooth finish. Has a nice charcol black matte that pops and is so cold (I'm a cold tone kinda folk). Not that into WT papers.
Also love messing with Ektalure, but that stuff's as scarce as hens teeth...
