I also have integrated weight pockets on my BCD, and I observed in Egypt when I needed a lot of weight to get neutrally buoyant that my weight pockets looked like they "wanted" to come out (granted I almost 3 kg per pocket). Mine snap in place though, so I don’t foresee them actually coming out. In the Red Sea (due to the high salinity of the water) more weight than normal is needed, and most divers that had the integrated system chose to wear the weight belt instead just because the stress the extra weight would cause the BCD. So, basically my advice is use a weight belt...probably will help prolong the life of the BCD anyway. Or at least use less weight in the pockets, maybe put half the weight in the integrated pockets and half on the belt.
