I travel to dive in warm water and have an oceanic Cruz bcd which has served me well but is soooo big and heavy it takes up much of my bag. I would like a travel BC and want to switch to back inflation anyway. I have been looking at cressi ultralight and air travel (I think air travel is discontinued however). Also zeagle scout. I am leaning toward the ultralight. I noted that there are no trim pockets. I always use my trim pockets in the Cruz for a few pounds but maybe won't be a big deal because back inflate? I'm guessing I will need a little more weight with these since they are so light ? Any thoughts on these travel BCDs would be appreciated. Thanks !!
