I like the competition chassis! Ive never owned the regular BA, just fondled one, but the competition chassis to me gave up nothing and added the magwell cut (which i really do like), and some neat forend features in exchange for the monopod.
I was also in the "i may like a monopod" mindset at first. I bought a monopod for my XLR chassis. Ended up selling it. I didnt like using it much at all. I liked rear bags much more. So to me, the monopod on the BA is more of a con than a pro.
