Depending on whether I'm using al or steel, wet or drysuit, and fresh or salt water I use either a belt with xs weight pouches mounted upside down or the bolt on plates with my DSS singles rig. With my doubles I use no extra weight. I mount the pouches upside down on the belt because I wear it under the crotch strap. If you are used to diving a jacket bc you may also find you need less weight altogether since the BPW set up has no inherent buoyancy to speak of where as some jackets may have as much as 5lbs or so.
