I'd recommend that you try a Zeagle Zena. I hated my Diva, sold it, bought a Zena and couldn't be happier. That said, note that I said to TRY a Zena, not necessarily buy one. There are a lot of ladies who love their ______________ and wouldn't even consider another BC (on the blank line insert any brand).
I will, however, tell you why I chose my Zena. I wanted a wing style (but not a BP/W) and a minimalist type of BC. The entire BC is completely modular, so you can custom fit it to you own body and diving desires. The shoulder section, the corset, and the wing are all modular, so you could literally have 2 wings, one for tropical diving with less lift, and a larger wing for cold water diving. If you lose (or gain) a significant amount of weight you can simply replace the front panel to adjust the fit to your new shape. You could also have a larger front panel to fit over a dry suit, and a smaller one for tropical diving in skins or thin full suits.
Best advice I could give someone based on my experience is to try on as MANY different styles, types, and brands of BCs that you can get your hands on before you buy anything. Do not choose your BC based on what anyone else has said about theirs since the most important thing is fit and comfort. Just because a BC fits me, doesn't mean it'll fit you, and vice versa.
