Really whatever you feel comfortable with I say. I have the Bengal (single) shoot amazing. I have Alien (dual/binary) shoots amazing. Really with the two, there is no noticeable difference in the draw for me, but you can tell the Alien has a little more zip on it. For me, I actually shoot the Bengal better for some reason, whether or not that has to do with the cams is a whole nother story.
Do what feels right to you.
