I break my stuff down quite a bit,but most of what i deal with is appliances. I get max value,it is kinda a relaxation thing out in the yard tearing up stuff, and it saves me time at the scrap yard,i have taken enough there i have a good rep for bringing clean metal,they dont spend a lot of time looking my loads over. however i have started getting more of the E-Waste,so i'm still testing as to how far to break them down.
