I agree with the responses about 44 lbs being, relatively, a lot of lift. But, perhaps, we should be asking, why do you believe you need more than that? Have you found that, in fresh water with a Ranger, you need more lift for instance? It might be presumptuous of us to assume that 44 lbs is enough, without knowing a little more about your diving configuration (beyond you initial comment about cold, fresh water).I'm trying to find a BC that has enough lift capacity. Most of the BC that I've seen only have 24 to 44 pounds a lift. I weigh 220 pounds and most of my dives are done in Lake Superior. I have used and really liked the zeagle ranger, but it only has 44 pounds of lift. Any advice would be greatly appreciated it choosing a BC.
