This oil-based-wax-based distinction is a little confusing to me, I had all colored pencils except the water soluble ones categorized as wax. I suppose you can use the same solvent for both. It does explain some of the difference in working quality.
I have been trying the polychromos for a couple years, and the working quality is somehow "short" compared to PC and frustrating to me.
I have a lovely metal boxed set of polychromos gifted me by my brother, and I honestly have been using it as a teaching set. I will try it in the studio a little while, I do have to say there are no breakages at all, after some fairly unkind treatment! But I suspect the working quality will still be annoying to me. I think I'm going to try a small number of Derwent color soft, I really like their water soluble Graphitint pencilsfor sketching out in the world.
I wonder about the caran d'ache line, Luminance. They are claiming to be non-breaking, and lightfast. They are also wax-based.... But, $4 each pencil. Holy cow that's a costly pencil! But if there is no breakage and I can allow original color pencil drawings to escape their light resistant vault, might they be worth it?
