It's a bust. They have 20 some 25# bags left over from another order. They couldn't give me much info about the product so I contacted someone who uses it frequently and they said it comes in fine, medium, and coarse. The medium is supposed to be about 1/16". Of course when I called Simplot to find out what grade they had it was fine. Nope not gonna work.

They told me it was really hard for them to get and they could only get it in full truck loads so that source isn't going to work out.
