Diva,
Comfort and fit are key. The option for weight integrated obviously is also a big plus, and having an air2 on the end of the inflater hose is a benifit. The Scubapro Ladyhalk is in my opinion the best out there today. I use the Nighthawk (Male Version) it’s the best I’ve ever used. Granted Scubapro equipment is a little pricey, but you just can’t put a price tag on safety and comfort. Good luck.
