My girlfriend uses the Mares Ariel (sometimes known as the Arial Dragonfly). She likes it very much. The weight integrate quick release is well designed but using the weight integrate pockets makes the side zippered pockets pretty much useless - this is the only drawback that I can see. I've examined a couple of Scubapro Ladyhawks and the weight pockets on those seemed excessively large. The Ariel also has a much simpler "wing" design i.e. the wing is not bungied like the ladyhawk's (I should say that both are back inflate BCs). The Ariel also packs very flat so is good for travel.
