I would also recommend using the buoyancy calculoator that stuck to the top of the BC section. It will give ballpark suggestions for both weight and wing size based on some weight numbers you punch into the program; buoyancy of the tank, both full and empty,( a single Al 80 swings from neg to pos during your dive as well), bc buoyancy, suit buoyancy, etc. Too big of a wing and you will be working a little harder to move around because you'll be dragging the excess material, inflated or not, through the water, same if your overweighted, weight changes a little if your going to be boat or shore diving. I like diving a few pounds heavier off the shore because the tides. You can move a little easier when your heavy on the bottom and the outgoing tide is starting to move after the slack, on the boat you have the anchor line to help you along, provided everything goes as planned.
If you are interested in getting the intergrated weight pockets, PM me, I have a set of the 32 lb pockets I don't use anymore since I switched to a steel backplate from the transpac.
