1.As far as discs go, it does not matter to me what brand they are as long as it is not generic. I usually use TDKs, Kodaks, or Fujifilms. 2.ABSOLUTLY NO TAO 3.Other than that I dont really care about sourcing or anything like that, just as long as it sounds good. 4.If something comes up or happens with the trade just be honest and let me know, I understand that shit happens sometimes.
