Home Distiller

I've done a lot of searching and can't find much info on anyone doing an AG oat vodka. I did find a couple of commercial micro-distillers doing an all oat vodka and they describe the light creamy flavor characteristics that is usually associated with oats. I'm thinking of giving it a go and looking for suggestions on what form of un-malted oats to use. I was going to use liquid enzymes on (here's where you come in) feed grade whole oats? Hot rolled feed oats? Crimped oats? food grade rolled oats (oat cereal)? What is your experience with oat conversion, flavors, or lack of, etc? I have a couple of bags of white wheat also that I'm going to try this with and wanted an oat product for comparison. Thanks
