hlsooner:My wive loves her Zeagle Zena. Back inflate, with all the other Zeagle benefits like ripcord weight releases.
The Zeagle Zena only has 16 lbs of lift. It is super awesome comfy, but you really need to look at where you'll be diving.
When I was diving BC's... I liked the Diva first, then Libra, and last the Sherwood Luna. I also dove a funny Italian Back Inflate. I really liked it, but it was still bulky.
Now, I have a Deep Sea Supply BP/W. It is the best fitting BC I've had. I wish I hadn't waited so long to get one.
