Currently I use 26# of lead when I dive in a 6.5mm 2-piece. Since I don't like carrying all of the lead in my BC, a Zeagle, I put a chunk of it on a weight belt. This works fine except for one thing, I use a crotch strap that goes over the weight belt due to how the BC sits. This is not a big deal since I can dump the weights in the BC if I need to. Where this becomes a problem is with a dry suit. The length of the BC means that the weight belt sits pretty low. In a wetsuit I still have hips protruding that keep the belt from going anywhere. On one occasion with a tri-lam drysuit I had the belt decide that it was going to get to the bottom before me and I caught it before it left my feet. It was not a comfortable feeling on the bottom wrestling with the belt in a silt cloud next to a drop off.
That being said, I just received the neoprene drysuit that I ordered. This seems much less likely to hold the weight belt where I would like it since the weight amount is going to go up. My question is, has anyone used a ditchable weight harness while using a weight integrated BC? With such a critter the crotch strap is no longer a problem and the harness won't slip off. Pulling a pair of handles on the harness pockets will dump the weight. I recently picked up such a harness and it can be set low enough so that it is below the bottom of the BC and feels comfortable when all of the gear, including lead, is on. (not tried in the water yet). The downside to this is that there are more straps involved and it is another piece of gear to be worried about (I look like an S&M aficianado with all of the straps).
