So Im trying to build or buy a BC that will help support the weight of the tank while humping in and out of shore dives. Like a regular backpack does, on the hips. My GF is a little taller than average and her BC just digs into her shoulders due to it not fitting quite right. Im thinking that a BP/W with a backpacking hip belt/cumberbun would do the trick. Anyone ever see something like this?
