I've got a pile of parts collected for a build and waiting for a few to show up. One thing I was considering was an air oil separator.

1. Does anyone have any advice on these?
2. I know that they are theoretically beneficial for emissions/octane degradation, but I'm an evidence guy. Would I ever notice the difference between having one and not having one? What benefit would be noticeable to an owner?
3. I was considering the Grimmspeed AOS, which is "set it and forget it" style. I saw this thread recommending against that design

Can anyone explain the recommendation against it and what they would recommend?
