Our shop just got some in the other day. After looking at them, I'm tempted to use one for a teaching BC (my old Balance's bladder ruptured). Likes: rear inflate, back suspension system & the BP/W style belt (will allow me to carry my canister light easier), cam band placement allows for better balance of cylinder weight. Dislikes: It has the lower cam band for the cylinder with trim pockets, that puts ALL your weight (dumpable & non dumpable) around the waist, pulling the lower body down. I prefer to be perfectly horizontally trimmed out. I saw the cam band can be raised a little & bring the trim pockets up a little closer to my shoulders. The BC is a little busier looking in the front than my Balance was, but not too much. I have not tried one out yet,.... these are just my observations, but may get one to replace my old Balance.
