Go someplace with a Sigma and ask for powder fine or something similar. Try on similar snow. I think you'll find it works just as well and looks prettier.
Unfortunately, fine grinds aren't "cool" looking, so they are often pushed aside by hardcore wet coarse grinds that show off what the fancy machinery is capable of.
