FWIW, I am a woman diving with the Balance (men's version of the Libra). This is my first BC that I purchased used with only a few dives on it. I used it for a week on my first dive trip and I am definitely not happy with it. I had previously dove with a jacket style BC in my OW classes. I am now considering the Diva LX because it has features that I now know that I want that the Balance lacks such as a cumberbund, right and left shoulder dumps as well as a right rear dump and stainless steel D rings. I do like the hybrid nature of the Diva better also. If you have a chance to try the Libra in the water, look for tank instability as in shifting from side to side, an inability to lift the inflator as high as you'd like due to the retainer strap being too low on the BC and air trapped in the bladder while trying to dump in a horizontal position. I found I almost always had to be vertical to vent efficiently. One more thing to look for is the ability to place the tank lower on the BC so that the first stage is not hitting you in the head. Maybe the Libra is different but if it is simply the women's version of the Balance, these are things to look for. Good Luck!
