I am glad to hear you are not going beyond 30 ft cause a DS is not an item of "If i loose bouyancy control" but when. Most important is air in the wing for buoyancy and only enough air in the suit for squeeze relief. The inportance of a pee valve will come in its own time when its importance becomes clear.
Good lock and post again with your post dive thoughts.
