I roll fondant out on a vinyl or silicone mat with a swipe of crisco--no dust, no fuss. PS makes it sticky and CS makes it dry, so I avoid the powders all together.

I use cornstarch, but once I have the fondant on the cake and all smoothed out I buff it with the palm of my hand (I don't generally use fondant smoothers), and that takes care of it! Anything left is usually absorbed while the cake sits in the fridge or when I give it the final pearl airbrush finish.
Im going to try CS next time too, Will it work the same on chocMMF? I never know how to make the chocMMF look "clean".
Well, I don't use MMF so I can't vouch for how it works on MMF but you could give it a try. I would imagine the result would be similar. I use cornstarch on all colors of fondant. I just did a cake where there were all sorts of colors and details used (including chocolate brown and black) but I never had a problem with dusty fondant! Just a quick brushing off and it is gone.

Although I never use any powders for rolling (no benefits that I can see, and therefore, not worth the mess), I have seen people roll chocolate fondant out on cocao powder.

I am going to try the CS, but Im curious about the crisco. Do you still flip the fondant after each roll? Does it make it sticky? I will use this method when I use chocMMF.
Personally I do not flip it each roll, sometimes I do like 2 o 3 times (when I use crisco) and then flip it, it doesn't make it sticky I use little by little (as need the crisco) and is my favorite method to roll the gumpaste or MMF.
I hope this can help you
