I have the prior model which is actually a balanced first. I chose it as we use 50% (and I got a smoking good deal on it). The only dislike is it came with the most awful mouthpiece. It is so soft, it's almost hard to hold the regulator in your mouth by only your lips. I feel I can't "relax" my jaw at all when on this reg with the factory mouthpiece. Other than that, I'm liking it very much.
