Depending on how much weight you normally carry and what BP you chose, you may not actually need to carry any additional (ditchable) weight at all. SS backplates are typically about 5 - 6 lbs negative, alu plates around 2 lbs. If you still need to carry additional weight, and are comfortable diving without ditchable weight, you could either use a weighted single tank adapter (assuming that you do dive singles), or you could use a channel weight or V weights. You could also install trim pockets on your tank straps that will accommodate standard hard or soft weights. If you are not comfortable diving without ditchable weight, there are still a number of options that you can pursue. One of them would be to simply carry a weight belt as you probably do now or you could purchase weight pockets that would be installed on your waist belt (although that may prevent you from installing either a canister light and/or additional utility pockets on your waist belt.
