I have dove many types over the past 3.5 decades -I like the lighter ones for travel but also l like to float head up if waiting for pick up. Back wings do not do that well. I have had a few. I now like the newer style Go travel BCD from Scubapro. I had an older one but they revised the style and they weigh under 5#s now-good for head up floating on surface as well as light enough to pack well-I'm sure there are now many brands that will follow suit. Zeagle's are also very well made BCDs-check out the weight of any BCD` before you buy and think about how you like to be on surface (orientation) in a long wait for pick up.
I think last I counted I owned 9 BCDs and as I speak I have 3 on flea bay for sale now.Sold one last week as well.
The other main thing is will it get in the way of taking photos-most modern BCDs do not.
