Yeah, the advantage of a super pastel is, you'll only get pastels, no normals.

The disadvantage is, you'll only get pastels! A super to a normal can't make any supers.

Pewters or bumblebees make 1/4 normals, but also 1/4 pewters and bumblebees.

... and I can't think of any other supers currently available for under $500?
