the lower the offset you go the more "hellaflush" you'll be, BUT the more work you'll need. You should first consider how far you are willing to go with fender work(and paint work), how much camber you are willing to run, and how much stretch you want. I'm guessing you have A LOT of research to do. Look throughout this section and the gallery to find your answers
