Nice pickup.
What do you expose your pins to in a HUO environment that makes you think screened art will hold up better than decals? I usually see accidental scrapes in art on HUO pins, and I don't think one would hold up any better than the other. And don't decals usually have more detail (even though Stern puts them on a little sloppy sometimes)? Wouldn't Quorra look better with higher definition decals?
I don't think I'd personally pay more for one option over the other, FWIW.
