thought that I would let you know that to go back and forth between Sub and Poly, just go to the convert, sub to poly and Vice versa. To go back to your original poly count, make sure your options are set to Vertex. Don't be afraid to go back and forth, I do it all the time, to make sure things look ok. Try to keep it as low poly as you can b4 you convert to SUbdivisions or else you will get unwanted waves. Let me know if ya need anything, I still need to send you that scene file, sorry! I will try to do that by Wed. Thanks,
Brian
