For a 180 No Comply your gonna want to set up with your back foot on the tail ready for a good pop and your front foot where ever you feel comfortable, I myself usually just set it straight across the board covering the front bolts. The key to this trick this the initially taking your front foot off the board without disrupting popping it with your back foot, just put pressure on your foot and slip it off and then pop the tail with you back foot as you would a 180 or something. Start turning your shoulders as you would a F/S 180 while guiding the board in the desired direction with your back foot. Now all you have to do to complete the trick is put your original front foot back on the board, and there you have it. Now get them down like Justin Strubing and you'll be set...
